"After 39000 miles and 4 1/2 years we still love our 3500 Sierra! We are the type that trade cars very often, generally within 2 years, and we have been through 12 other vehicles since buying the truck and it is NOT going anywhere! It currently is used to tow our 5th wheel toy hauler that we live in full time and it does it like a champ! Sure the new ones have great bells and whistles, but the truck is the one thing we own that is so dependable we aren't even considering a switch. We've owned all but one of the other brands of HD trucks and would likely stick with GMC from here on out if we needed a new truck."
