Is this going to be a "hauling" type of trailer for lumberyard and dump trips, or something else? It might make a really neat alternative to a modern camping trailer. Maybe a couple of bunk beds and a simple stove/micro/fridge setup. A window or two and a skylight fan. Paint the interior a light color. Carpet. You could really do this up bigtime and have something really unique to tow behind your running panel. I like the idea suggested earlier of using another panel rear end to graft onto the front of this one. (More destroyed trucks!) And then it would have a vintage look that perhaps looks factory built, and be more aerodynamic as well.
