We're looking for a new work truck. Needs to be a 1ton 4x4 Chevy dually.We prefer a 6.2 diesel if it's an older rig. Needs to be in excelent shape and use no oil. Also needs to have 13'-14' feet of frame behind the cab. Would really like a 92'+ 3500hd with the D70/D80 combo . Just looking to see what's out there before we buy.
