Why upgrade if you don't have a burning desire for a new one? Drive it till the wheels fall off while you save up to pay cash for the next one. My opinion anyway.

I've got a 2005 Duramax (lly) and am in the same situation. It's paid for, gives me no trouble and got 18.5 mpg on a road trip to FL last month. It's my daily driver.

I'm keeping this phucker until it dies! :D

i have an 2002 duramax with 212,000 miles, runs as good as the day i bought it! but i love the new bodystyle

I'm with OldSchool, I got a 2004 GMC Dmax that has 60K miles and has been paid for for years. However, I got me a beater for commuting and only drive the truck on weekends to tow the boat. I plan on keeping it til it dies (or I do). I do like the 2500HD Denali though (except the $65K price tag!)

I've got a 2001 3500 gmc duramax, and it's nice, but i got better mileage with my pre emisson 2006 lbz. I'd keep the 06.

I would Keep it. Sounds nice, custom, plus its the best year made. The new trucks are all awesome minus the emissions. You could use the money you save on upgrading your current truck more. Add some billit to the trans, fuel pump, tuner, air intake, turbo, cp3 pump, exhaust, suspension (at least nice shocks), in dash DVD navagation, some nice focal speakers and amp, etc.

Please don't get a dually when you do upgrade, you really don't need it. Unless your towing a 50' on a tilt across the country every week!

id keep it. if you get rid of it, you'll probably regret it. Especially since you love it already. I have an LBZ with over 100k and love it. no problems at all.

Keep it or pay out the ying yang for a new one.

I've been trying to find a used, reasonably priced d-max for quite some time and gave up......

Instead, now I'm looking for a house on the water with a boat lift. If that wish comes true I'll sell the 2500 Burban and buy a daily driver. I haven't had a car payment since 2006/7 and love it!

Def don't drive one of the new GM's or Fords though, you may end up buying one when you see how nice the new trucks drive and quality of the interior lol. No joke, these new trucks drive unbelievably nice for their size now. My friend had an 06' with the LBZ and I told him the same thing, he ended up testing an 11' F-350 and GMC and came home with the F-350 lol. He really didn't need a new truck but it blew him away how nice it was.

New anything is always nice but nothing beats FU money in the bank.
