I have a short bed heavy duty diesel and will never go back to a long bed. With the longer cab it's much nicer. My dump trailer has a 10' bed and I have 2 flatbeds. One is a deckover with a 16 X 8.5 bed. The other is a tilt deck wit a 22 X 7 bed. All 3 trailers can carry more weight than the truck bed as well. The short bed works just fine for me. Each trailer has a use that they do better than the truck. In fact he truck can't do it and a long bed wouldn't change that. It's too high too short and too narrow. It also won't dump. And as for buying a seperate dump truck that would make no sense at all. It would cost more than all 3 trailers. The maintenance would cost more. And it could not do evreything I need it to do so I would need at least 1 of the trailers.
