I would look for a long chassis truck. I know that will probably be medium duty but that should work good. You should be able to use a cargo box which wil be plenty strong as well as save a lot of work & $. People confuse the amount the amount of horsepower wanted with the amount needed. You can have a little smaller engine it just means that you will slow down a little on big hills. Remember its a big truck not a sports car.
