We purchased 4-Chevy Dump Trucks, Model #C6500 in 2004. Needless to say we have to replace both gas tanks on all four dump trucks, it's a bad design and they are rusting out. We know we are not the only GM Chevy Dump Truck owners out there and we know other owners are having the same problem. But no GM dealer has these tanks and we use these dump trucks for everyday operations here at the Military Base. I need to have them switched out before winter as they are leaking and GM has no extras and/or does not have a build date for them? How are companies supposed to operate owning GM Products and not able to get parts for them? read full review »
