My solution to the short bed is going to be a custom (home) made cap that extends over the tail gate, which will be lowered. It will be made of wood and not have any built in interior features. It will look like a camper from the outside but will not have the 'tub' part that fills the space below the rails. I'll post pictures when I get it built. Hopefully next spring. The size will be determined by how tall it has to be to fit mt. bikes standing up, with the front wheel on.
