Buy a new 3/4 ton crew cab gasser work truck for less than you would pay for 100,000 mile used up trim 1/2 ton truck. If you want leather, etc get it done aftermarket. Revel in the fact that you have a 3/4 ton that has far better brakes, frame, axles, etc than any half ton made. Never worry if your camper is too heavy or if the camper is wagging the truck tail again. Thank me later.
