The trailer as it turns out used to be a "dirt bike" hauler, the kind that has the 4 rails attached so that the "dirt bikes" could set in. So that's how big it is if you can picture that. The total floor space that I laid the diamond plate down is only 6'4" x 8' just enough for 2 Harley's to ride on the back. I want to paint the surface of the diamond plate with a "bed liner" kind of paint........does anybody know of a good brand to get for this purpose? And again thanks for all the ideas and support.
