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.
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.
I bought my Duramax Diesel 2500 Hd crew cab to pull a 36 foot fifth wheel. There is plenty of power; however, have had a few problems. The speedometer failed at about 60000 miles and had to be replaced. I have read that this is a common problem but there is a class action lawsuit and I plan to turn in my 478.00 receipt and hopefully get reimbutsed from GM. The engine light came on and paid to have the code read which was relatively meaningless but haven't had any more problems with that. I added a Superchip which is amazing how much perfromance improvement. Have heard that some people have burned up transmission with Superchip but I always reset to towsafe prior to pulling anything.
