I have been a GM man as long as I can remember. It started with my uncle's '69 camaro. My first truck was an '83 GMC High Sierra, SB 4X4. I recently sold my 2005 Silverado 6.0 CC SB 4WD. I used it the past 2 summers to tow my 8,000lb toy hauler. My son, Dillon races dirt bikes. I bought my 2006 GMC Sierra SLT in Florida. I rode 15 hours from VA. to Sarasota with a truck driver friend to get it. I loved it the first mile on the road home. I loved it even more the firts trip to a race with the trailer in tow. I have been lurking a little while and realize there is a lot that can be done to enhance the DMAX. I hope it serves me a long time.
