Search "Scotchguard" at the top of this site and you'll get quite a bit of opinions. My opinion is that the camper you buy (unless you plan on never selling it) will never return the investment you make from that purchase. If you also search "covering my camper" it will bring many opinions on covering one or not, the bottom line I took from that post is that these campers are designed to be outside and handle the elements on their own. Just my two cents.
