Some units are fiberglass with a few decals on them. They can look good but they are not full body paint. Those with full body paint have all of the fiberglass pained and might have the graphics as decals or painted on. The more colors that are painted on the greater the cost of the unit. Full body paint is just a preference. It costs more and might have a higher resale value but it is just the buyers preference. However there are all grades of fiberglass. The higher quality is very smooth and the lower cost fiberglass has a rough finish. If you go to an RV show and just walk around you can look down the side of all of the units and see the difference. I hope that this helps. Good luck with your search.
