Very nice truck. Lots of power for pulling my 35 foot race trailer. Good on fuel about 21 highway 18 in town. I put the banks 6 gun chip in it. Very fast. Sounds good and has lots of power

This truck pulls a 30 foot RV travel trailer with absolutely no problem. Using the tow button helps slow everything down with ease. This truck is much more quieter than Dodge or Ford. It has lots of power and looks great, unlike it's competition.

i love my pickup, hauls my 40HP massey with bucket and brush hog like it's not even there. with banks big hoss bundle it hauls balls and doesn't think twice. awesome truck wouldn't give anything for it. it's dependable, and with all the mods it catches eyes everywhere i go. as of now, until ford puts out the 6.7L would only recommend a duramax. cummins is good but everything around it is crap and rides like a semi. duramax is king right now. i just can't say how much i love my pickup.

Fuel mileage is poor at best. Engine surge and hesitation. Driveability is very eratic. Vehicle runs hot, fan runs excessively. Tranny and engine temp gauges always show 210 or better. All this while running vehicle empty. When towing all of the above is off the charts. GM answer is that all is normal.

Good, but not great

This diesel was an upgrade from a gas Dodge RAM1500. Pulling a 7,000lb trailer now seems effortless. Turbocharger takes a long time to engage and gas mileage wasn't as good as I'd expected for a diesel- about 12.5 pulling trailer which is disappointing since over 20 without. Just had 3 injectors replaced under 100K Duramax warranty which I believe was a known problem in all GM diesels from 2002-2006. No recall, of course! No significant change in power or mileage with the new injectors. I hate that GM always adds a $95+ "diagnostic fee" for the computer hookup with any service. Also- computer's trip timer hasn't worked since purchase and the stereo speaker sound is absolutely awful.
