So my wife and I (mostly my wife) bought a little 22 foot camper at a campground outside Bethany Beach. It is a 2021 camper so fairly new and I guess it is in OK shape. Don't know squat about campers. Anyway, I'm gonna go down in two weeks for a few days and wanted to properly clean and inspect the rubber roof (I guess it is is rubber?). Is there a NAT approved cleaner and/or conditioner I should us?
