A couple other items to consider:
Besides wear and maintenance, the other issue is trade-in or resale value. From experience, if FBP is an option and it is not on a coach at trade in the owner will take a hit on the trade in value.
Body repair for FBP is more expensive and may be reflected in your insurance premiums. If something happens to my coach that requires body repair, most areas will require someone shooting 4 colors of paint rather than shooting one color and then applying stickers.
Between my prior coach which was not FBP and the current one that is, I can wash this 38 foot coach in half the time and when it is washed and waxed it looks good rolling down the road.
