April 28, 2008Apologies in advance for the long winded post.
I'm working out of the country and will be in the market for a new truck when I get back to the states. I had a 2003 GMC Dmax 4x4 that I loved, but it lacked a little when compared to my buddy's Dodge's when towing 10,000+ pound trailers. Empty, they didn't stand a chance though. I had 4" turbo back exhaust, S&B cool air intake, an Edge Juice w/Attitude tuner, and was running 265/75r16 tires.
Things that bugged me about the truck.
Delayed throttle response, mash......thinking.....uh....almost there... GOOOOO!! Too late to get out in front of that yahoo on the highway doing 68 when the truck you're approaching is doing 71...
Allison shifting, like there were government officials in there debating when to drop a gear and get moving.
GM 4x4 IFS eats tires like there's no tomorrow. 30,000 miles max out of any tire I ever put on there, including Michelin 60,000 mile tires... Yes aligned, yes re-balanced, yes correct pressures. Never mattered.
GM recalls/fixes, tailgate cables, fuel filter, seat belt loop, injectors, intermediate steering shaft, stuck open thermostat... Had it 2 1/2 years and it went to the dealer 5 times for recalls and/or repairs.
Other than that, I loved the truck, took great care of it, and drove it every day.
So here I am trying to decide on a new truck with all the new emissions junk. I'm debating between a Dodge 6.7l and a new Duramax. I won't buy another GM 4x4 until they fix that tire eating problem. I've seen the peak HP and TQ numbers, but honestly guys, peak means Jack **** to me since the Cummins seems to have more level and sustainable power curves, most likely from being an I6 instead of a V8. I've read a bunch of issues from the Dodge guys' forums with the DPFs, EGR's, Turbos sooting up and just stopping, so now I'm a bit skittish about the new 6.7l.
Before I go drop upwards of $40k on a new truck, I'd like to get some real opinions from 07-08 Duramax owners on how well their trucks are holding up and how many trips y'all have had back to the dealership for anything.
I really do still like the GM better, but when looking at dragging around 10,000+ pounds on a more regular basis, I honestly would not want to do it with my 03 again compared to the 04 Cummins that walked right past me up the same mountain passes with the same load, hardly straining and getting better mileage to boot.
