Full body paint cost 6% of the 2350 cost without options. Also think about tradein or resale value. Try Kelly blue book or nada and see the difference on a 5 year old motorhome. Subtract that number from the cost of full body. Now think about which looks best to you. Even if you like a single color, like white, you should ask Earl about the cost of just one color.
I have had motorhomes both ways and I think the full body is easier to keep clean looking. When I was a young man I washed and waxed the motorhome every month. Boy did it ever shine. Now I use gel coat wash and wax. I can be really lazy some times. Any way this hobby is about having fun not having to work. I can stay home and work.
What you want is what counts.
