What would be more durable against scratches and scuffs from branches and bikes and stuff - full body paint or the standard fiberglass gel coat?
You should first understand that "gelcoat" as refers to RV siding is often very different in composition, durability, and thickness from that used in molded fiberglass operations like boatbuilding and some small molded trailers.
With filon-type siding typically used on stick-built RV's, many such coatings are very thin, which means that there's limited ability to polish out those scratches that do occur.
