You are correct, and I was thinking of something else. Cast aluminum front differential housing on all Subs and Silverados.

I averaged 23.2mpg over a ~225 mile round trip this Spring in a 2015 Tahoe 5.3L 4x4. Constant freeway speeds at 62 mph. The 25mpg photo was of the first 20ish miles. It's very easy to get better than 20mpg, and I believe their official EPA rating is 22mpg for 4x4. I could get 20ish around town...

All wheel drive (no low range or 2wd), coil sprung rear, autoride, all half ton except the motor. Since you're buying it to tow a fairly heavy trailer, all of the differences that make up the 3/4 ton are exactly what you want: Bigger frame, bigger brakes, bigger wheel bearings, bigger axles...

The newest 2014 or 2015 with the direct-inject 6.2 is an incredible motor (420 hp / 460 lb-ft). The new 2015 with the 8 speed is really the best of the best. Awesome power at any rpm, yet very fuel efficient in the real world. I've gotten over 25 mpg on a freeway run in a 6.2 6spd crew 4x4...

+1 for the 8.1L I'm at 260K miles, all original drivetrain, no issues .... but the 6.0L is a good motor too I prefer the multiplexed electrical of the 2003-2006, and the seats, and additional features. Even as you develop preferences to one year or one drivetrain or some particular...

It's the biggest motor choice, the 8.1L (496 cu in) big block... you wouldn't buy one unless you had the need. But with 3.73 gearing and large 32.8" tires, I get about 10-11 mpg around town, and 14-16 mpg on the freeway, empty. When hauling a trailer, it gets about 10-11 mpg all the time. It's...

I love it when people are buying used trucks and are willing to pay thousands more for a truck they believe will be "more reliable" than a truck they fear will be "less reliable".... even if it's the nameplate that makes it reliable/not-reliable (which is BS, as it's a used truck and the...

The 6.2 and later 6.5 turbo diesels weren't medium-duty diesels like the Cummins, and they suffered numerous maladies. They weren't known for their strength. However, if you knew how to care for them and take care of them, they could be coaxed to many miles of service and decent fuel economy.

I've had several Suburbans and zero issues with reliability. My current rig has 260K miles on the original engine, transmission, transfer case, axles, alternator, starter, etc, etc. Two of my power windows are giving me issues, as is the power lock solenoid for my rear liftgate.

You had the choice of three engines: 5.7L Vortec V8 - expect 12ish around town, and 15ish freeway 7.4L Vortec V8 - expect 10ish around town, and 13ish freeway 6.5L Turbodiesel - expect 14ish around town, and 19ish freeway Tires and gears will make some difference +/-

The newest version of the 3.5L EcoBoost makes 400 lb-ft at 1250 rpm, and peaks at 460 lb-ft at 2750 rpm. It is currently available in the Lincoln Navigator and will soon be available in the F150 Raptor. My 8.1L gas makes 455 lb-ft at 3200 rpm, and 400 lb-ft at 1250 rpm The "holy grail" 24v...

In theory, that might sound true. In reality? Have you seen the weight difference from a gas V8 to a turbodiesel? Pick a brand, any brand. The "weight savings" in fuel is absolutely dwarfed by the weight of a diesel motor. A Cummins 5.9 6BT, larger radiator, turbocharger, intercooler and...

That Duramax forum is excruciatingly slow. It loaded a page a minute, if that. Luckily, I went to your site and the pages loaded within seconds. I was able to make it through the entire 5 part build (so far) and read every post. Took me quite a while, but it was fun. Great build! It seems to...

Are you getting a brand new truck? Couple year old truck? Several year old truck?

Great find! Loooong truck

A 2007 Suburban is a fantastic tow rig, and shouldn't struggle with a 7x14 trailer. At 173K miles, absolutely anything could fail. I'd pay specific attention to wheel bearings, fuel pump (and don't run it under 1/4 tank), and u-joints Check the idler pulley/tensioner Any fluids and filters you...

Or buy a Tacoma, replace everything with cool aftermarket parts, still have less power and get worse fuel economy in a smaller truck, and still spend MORE overall.... yet there are dozens of those "Expedition Tactical Grade" rigs all over build threads a couple forums up

Which truck has their 3/4 ton gasser motor? None, in fact.

Yeah, they may want to re-do that with a 3.5L V6 EcoBoost. But there's no re-do for the 5.7L Ram and 5.7L Tundra. While there isn't a clear winner in many people's mind, I think there is a clear loser in the empirical data here...
