I bought a new GMC 2500 in late '07 with the 6.0 classic body style.
Got it brand new for $20k.
Mine's 2 wd, 8ft bed. Just a work truck but it is very nice, cloth seats, chrome etc...
Around 85k on it now and I've done regular maint., no problems.
Gas mileage without a trailer is around 12 around town.
Pulling my tandem trailer loaded is around 8-9 and a lot of my driving is hwy.
Love it and will probably get another one next year.
Remembering all my departed friends.
