Our buddy James doesn't realize it yet, but he wants a new truck. Of course, he'll still say, "I don't need a new one. Mine is fully paid off."

But we've never met the truck owner who doesn't toy with the idea of upgrading his rig, and especially now that all three of the big hitters in the heavy-duty category are hawking new product.

James might be playing it cool, but we know he wonders if he couldn't do better. So we've taken matters into our own hands by acquiring each of the potential replacements for his pickup. Here's the list: 2010 Dodge Ram Pickup 3500, 2011 Ford F-350 Super Duty and (filling in for the Chevrolet Silverado) 2011 GMC Sierra 3500 HD.

These are serious heavy-duty 1-ton pickups. Each has diesel power, four-wheel drive and single rear wheels, and each wears a crew cab and a 6-foot-something short bed.

Of Rumbling and Getting Ready
James regularly uses his bright-yellow 2005 Ford F-350 Super Duty to tow a bright-yellow, triple-axle enclosed trailer. Inside you'll find one of his bright yellow cars, so the trailer's loaded weight can range from 11,000-13,000 pounds. If you've got a serious pickup, you're probably a serious tow guy, which is why we've knocked on his door before and asked to borrow his trailer. Of course we're obliged to provide our own ballast vehicle, so we're bringing along 3,860 pounds of decidedly un-yellow 2009 Audi A4 Avant to increase the loaded weight to 12,480 pounds.

If you're thinking towing is a big part of our test plan, you're right, since we'll be visiting 11.5-mile Jacumba Grade, our usual tow-test slope. But of course no one tows 100 percent of the time, so we'll spend a considerable amount of time driving these trucks trailer-less on the straight and level. Finally, we'll put the trucks through the usual paces at the test track.

Meet the Fresh Meat
We last did something like this with HD iron back in 2006, although they were enormous trucks, duallys with 8-foot beds. This time around the trucks are all a bit more usable in an all-around way, and each can be had with a six-speed automatic transmission, each has an integrated diesel exhaust brake and each has an electronic trailer-brake controller.

Our 2010 Dodge Ram Pickup 3500 Laramie Mega Cab 4x4 is an example of a truck that had its extreme makeover in 2010 with new sheet metal and a fresh interior. This truck's 6.7-liter Cummins turbodiesel inline-6 produces 350 horsepower and 650 pound-feet of torque, so the Ram is vulnerable in the power department. On the other hand, its 24,000-pound Gross Combined Weight Rating (GCWR) and 16,450-pound tow capacity are impressive.

The lineup of 2011 Ford Super Duty pickups has been redone, notably with the replacement of the controversial 6.4-liter V8 PowerStroke diesel built with Navistar. This Ford F-350 Super Duty King Ranch Crew Cab 4x4 features the all-new 6.7-liter PowerStroke V8 turbodiesel designed by Ford, and it churns out 400 hp and 800 lb-ft of torque. Equipped with the standard 3.55:1 axle ratio, this F-350 has a 23,500-pound GCWR and is rated to tow 15,800 pounds.

The lineup of 2011 GMC Sierra and Chevrolet Silverado HD pickupsfeatures new running gear and a substantially beefier frame beneath familiar sheet metal, while the revised 6.6-liter Duramax V8 turbodiesel makes 397 hp and 765 lb-ft of torque. We've brought the 2011 GMC Sierra 3500HD Denali Crew Cab 4x4 because the top-level Denali trim is newly available on GMC's trucks. With the standard 3.73:1 final-drive gears, this Denali carries a 24,500-pound GCWR and is rated to tow 16,800 pounds.

3rd Place: 2010 Dodge Ram Pickup 3500 Laramie Mega Cab 4x4
Let's get one thing straight. That is, 3rd place does not make our Dodge Ram a bad truck. There's a lot to like here, and it's the least expensive truck in this group.

We're using pricing for the 2011 Ram to keep our test scoring on the level (it works out perfectly because the electronic brake controller is now standard instead of optional). The Laramie's base price of $51,465 might seem high, but that's largely because the diesel engine is baked into the price as standard equipment. What's more, dual rear wheels are standard, so you can deduct $995 if you pass on the dually configuration like we did.

And then there's the Mega Cab. It offers a massive 44.2 inches of rear legroom, plus rear seats that recline into a void for cargo that's big enough for a couple of carry-on suitcases. Go for an equivalent Laramie 4x4 with a mere Crew Cab (like the other trucks here) and you'll save $700. Dressed in heated and cooled leather seats, a navigation system and other goodies, the Mega Ram's final price comes to $56,945.

The front half of the cab is every bit as welcoming as our fondly remembered 2009 Dodge Ram 1500 Crew Cab. The interior design and materials say "truck" without hitting you over the head with it, the controls make good sense and the seats are firm and supportive over the long haul. The Ram is also the only one here with side curtain airbags.

Ride comfort is another matter entirely, as our 3500-Series Ram 4x4 is more stiff-legged than either of its opponents. The cabin isn't the quietest one here, but it's not far off. But our sample truck sometimes emits an annoying drone when cruising at about 60 mph.

When the Ram's steering is discussed, this 4x4's solid front axle produces a surprisingly natural level of feel and response. The Ram backs it up by winning the slalom with an effort of 56.5 mph (not so speedy, but it's a big truck, after all). A stop from 60 mph takes 152 feet, which sounds awful until you realize this behemoth weighs 7,640 pounds.

Things go a bit south when we press the Ram's accelerator. No surprise, since it gives up about 50 hp and well over 100 lb-ft of torque to the others. It takes 9.1 seconds to reach 60 mph from a standstill (8.8 seconds with 1 foot of rollout like on a drag strip), a second quicker than a Prius but 1.6 seconds behind our Denali. All of 16.8 seconds go by before the Ram 3500 finishes the quarter-mile at 81.7 mph, no less than 6 mph slower than the GMC.

With the trailer in tow, the Ram's performance is more of the same. It crests the summit of Jacumba Grade in 12 minutes and 12 seconds, some 36 seconds behind the winner. Minimum speed sags to 49.8 mph in the steepest section, slowest of the bunch by more than 7 mph. We didn't directly measure time spent at wide-open throttle, but the Dodge languishes below our target speed window for 6 minutes and 41 seconds with the throttle mashed — that's well over half the trip.

Through it all, the Ram's rear suspension handles the tongue load with ease, and the truck remains steady and composed through the bends, bumps and crosswinds on the winding descent. The diesel exhaust brake is effective, but it also isn't quite as proficient or adaptive as the other trucks, so we have to prod the brakes a time or two.

No fuel economy ratings exist for heavy-duty trucks, so we measured our own. Unladen, the Ram rolls along at 14.2 mpg. This drops to 6.4 mpg on our 35-mile tow-test loop. Both are the lowest in the test, but not by much.
Bottom line: The Dodge R
am 3500 is a very good truck that needs a stronger engine to keep up with the others. Of course, those who don't tow much (or live in places where it's as flat as Kansas) might not care.

2nd Place: 2011 Ford F-350 Super Duty King Ranch Crew Cab 4x4
The 2011 Ford F-350 Super Duty King Ranch Crew Cab 4x4 makes the most horsepower (400) and generates the most torque (800 lb-ft) in this group, so why doesn't it take the prize? For one, it's mighty expensive.

That's not the whole story, but let's start there anyway. Compared to the Dodge Laramie, the $49,725 base price of our King Ranch appears lower. But then you have to add another $7,835 for the optional diesel engine. A moonroof adds another $995 and 20-inch rubber adds $1,375 more. Navigation ($1,875), bed upgrades ($1,075) and other assorted options inflate the as-tested price to $64,965, of which $2,500 represents fluff we could do without. Yet even without that stuff, the F-350 would still be the priciest truck here.

Inside the cabin, the King Ranch lives up to its price tag, as it looks like a saddle shop, with the brand of King Ranch stamped and sewn into the leather. The Ford crew cab might not be as long as the Ram's Mega Cab, but 42.1 inches of rear legroom is still mighty healthy. The spell is broken because the dash screams "truck" louder than necessary. The glovebox door is even molded with those indentations you normally find at the bottom of a truck bed. Ford tough, and all that. We get it.

Thankfully, Sync is part of this F-350's array of features, plus a new trip computer that has clever displays, including programmable trailer settings and fuel consumption feedback. The Ford is also the only truck here with a telescoping steering wheel. And the F-350 has power-operated extendable tow mirrors, while the Ram and Sierra's tow mirrors must be manually deployed.

Once under way, the Ford is a mixed bag. The ride is smooth (for a 1-ton truck) and admirably quiet. You know there's a diesel under the hood, but the sounds are muted. But that telescoping steering wheel barely feels connected to anything and it takes lots of steering lock to get anything done. All together, the F-350 does not inspire in the corners, and steering it is like tapping a microphone while asking, "Is this thing on?"
The F-350's character affects its behavior on the track as well. It reluctantly navigates the slalom at 52 mph, some 4 mph slower than the rest. And not only does the F-350 take 159 feet to stop, brake fade (not to mention the stink of smoldering brake material) makes an unwelcome appearance. The physics of this package help explain some of this, as the F-350 stands 80.8 inches (2.5 to 3.4 inches taller than its rivals), weighs 7,900 pounds (260-400 pounds heavier) and has a fractionally narrower track.

The F-350's weight and size might also be the reason why the PowerStroke's big power numbers don't translate into stomping performance on the drag strip. Sure, the Ford bests the Dodge, but the margin is thin. The F-350 accelerates to 60 mph from a standstill in 8.8 seconds (8.4 seconds with 1 foot of rollout) and covers the quarter-mile in 16.5 seconds at 83.8 mph.

Towing is where the Ford comes into its own. Jacumba Grade's 11.5 miles are history in 11 minutes, 44 seconds, only 1 minute, 9 seconds of which are spent under the target climbing speed. Even at its worst, the F-350 loses only a little pace, slowing to 57.6 mph. Through it all, there's not a single shift, as the Ford transmission settles into 5th gear in tow-haul mode and stays put.

But on the way up the throttle feels somewhat reluctant to respond to small adjustments. Like the vague steering, it's a bit unnerving. It's not an engine issue; it's more of a throttle pedal calibration characteristic, and we're not big fans.

The F-350 does as well as we could want downhill, as the six-speed transmission and exhaust brake make all the right moves. The Ford is the only truck here that doesn't have an exhaust brake switch on the dash — its activation is controlled exclusively by the ECU in response to conditions.

When it comes to the consumption of diesel fuel, the Ford isn't much better than the Ram, as the F-350 earns 14.6 mpg in mixed normal use and 6.5 mpg on the steep tow-test loop. (We call this a tie.)
Bottom line: The 2011 Ford F-350 King Ranch 4x4 is a strong truck that tows quite well. It's quiet, smooth and well equipped. But it's big, heavy and aloof to the point that even the driver can sometimes feel like a passenger. And the price is substantial.

1st Place: 2011 GMC Sierra 3500HD Denali Crew Cab 4x4
The 2011 GMC Denali 3500HD Denali Crew Cab wins this comparison by a narrow margin primarily because it's a well-rounded truck. It performs well, is efficient and doesn't cost a lot of dough.

Starting at $47,150, the top-of-the-line GMC Denali has the lowest entry price of our trio. But because the diesel engine ($7,195) and the mandatory six-speed automatic ($1,200) are priced separately, diesel power is actually an $8,395 jump. Once you add navigation ($2,200), a rearview camera ($450), a heated steering wheel ($150) and other options, this Denali prices out at $59,545.

Things don't start out well for this GM truck because the Sierra's redesign for 2011 has skipped over the cab. Yes, the new Denali trim is handsome, but the center stack with its fussy tiny buttons still annoys us. There's room in the front of the cab, but adult-size passengers might be troubled by the 39 inches of rear legroom in the back of the Sierra's crew cab. The other trucks in this roundup have it covered.

Turn the steering wheel and the GMC begins to show its strength. It rides on independent front suspension as before, but the geometry is utterly new and all of the components have been significantly beefed up. The 2011 Denali goes down the road arrow-straight and turns into corners with a predictable honesty that the Ford can't manage.

And the Sierra 3500HD has a reasonably quick steering ratio, so less input is needed to do just about anything, such as make a U-turn within 50.5 feet, the tightest turning circle in this bunch. At the track, the GMC slips past the slalom cones at 56.3 mph. Stops from 60 mph take 147 feet, the shortest of all these trucks. Perhaps it's no coincidence that the 7,500-pound GMC is the lightest of these three.

But the throttle is the Sierra's biggest trick. Power delivery is deceptively smooth on the way to a 7.5-second sprint to 60 mph (7.2 seconds with 1 foot of rollout) and the Allison 1000 six-speed automatic makes quick shifts until the quarter-mile ends in 15.6 seconds, 87.7 mph and total domination of the F-350 and Ram 3500.

With a big yellow trailer latched onto its hitch, the Sierra does almost as well. It surmounts the mountain in 11 minutes, 36 seconds, a handful of seconds quicker that the F-350. Throttle response is much more immediate and linear in the Sierra, allowing us to accurately hold the target speed with much less fuss on the lower slopes. Once we encounter the steeper upper sections, the Sierra has a similar minimum speed (57 mph), but it does spend a little more time (2 minutes, 44 seconds) at the bottom of our speed range during a couple short bouts of full throttle.

On the winding 6 percent downgrade, the Allison six-speed transmission and the diesel exhaust brake comfortably regulate the Sierra's descent speed. As with the F-350 and Ram, manual shifting capability is provided, but there's no need to partake. Engage Drive, select tow-haul, set the cruise and you're done.
Through it all, the Sierra uses the least fuel. Our routine driving is good for 16 mpg, and the truck earns 7.3 mpg on the tow test loop, about 10-12 percent better than the other guys.

The 2011 GMC Sierra Denali wins because it does the important truck things well. It accelerates, brakes and just plain drives better in just about any situation, towing or not. And on the big hill it holds its own with the slightly more powerful Ford. On top of that, it costs significantly less to buy and it drinks less fuel.

What Have We Learned Today?
All of these trucks have improved significantly since our last heavy-duty roundup in 2006, and now none of them is a bad choice.

If anything, the 2010 Dodge Ram 3500 proves that standing still on the motor front is not a viable option in this crowd. The 2011 Ford F-350 Super Duty's commanding size and weight set it apart in this group and could become a liability as fuel efficiency and cost of ownership loom larger in the future, since such concerns certainly cut into its theoretical advantage here.

For now, the 2011 GMC Sierra 3500HD Denali is our idea of the winning combination, albeit by the thinnest of margins. There's no denying its strong all-around performance and good driving manners, but it's overdue for a new cab and a fresh interior. With those it could have won this contest by a landslide.

As for our friend James, he reminds us once again that his truck is paid for. But since he's a truck guy, he's always interested in a better ride and we've essentially done his research for him. When it comes to hauling his own trailer, at least, his choice comes down to two of the three. We'll poke our head around the back of his shop in a few months and let you know if a new yellow truck appears in his driveway.

The manufacturers provided Edmunds these vehicles for the purposes of evaluation.
