I think that beside looks funny to me because it's curvyness doesn't reall match the rest of the look. I was trying to think of a bed that would be slightly more fitting to the whole truck theme and I thought maybe a M715-ish bed would look pretty cool on there. Wouldn't be too hard to build, or make narrow, and you could do something more like a half a trailer fender instead of the non-lipped arch of a M715. Just kind of thinking out loud.
