That has a number of panels joined together. If you were thinking of going fiberglass, I'd recommend Bigfoot trailers. They'll definitely be more expensive than that, but they are clamshell construction with one big piece for the top and one for the bottom. The only structural seam they have is where the two halves are joined. I've had both a slide-in truck camper and a bumper pull trailer from them and they are impressive- very well insulated, nicely laid out, well featured.
