Thanks @seekoutbeauty . I am curious to see if @rino will have anything. I just figured it should get some sort of protectant once a year or something on the canvas.Nothing documented, that I am aware of. (@rino may know of something though)
I personally just air things out after a trip. If my awning looks dirty, I rinse it.
Pull the Mattress out or at least flip it.
I wash the camper like I wash my truck. I even use the same drying aid on the camper and it gives it a nice new look.
I recommend this stuff - It is like "voodoo magic amazingness" Beadmaker Drying Aid. Spraying it directly on the vehicle is fine, but I have noticed that when I spray it directly on the camper, it seems to attract more dirt/dust where I spray it. I find that doing the entire truck first, and then hitting the camper when I am done is best.
I use beadmaker on the awning bag too, and it works well. If you want to use something that is specific to vinyl and plastics for those pieces, like the awning bag, try something like Aerospace 303 UV protectant.
The thing that I struggle most washing is the chimney (because I am paranoid about water getting inside). I have now avoided it all together when washing, and at the end of the wash, I take my wet microfibers from drying the truck, and just wipe it down.
I am doing the same as far as washing the rest of the camper, though I will have to check out some of those products. Just using carwash products and then toweling everything down. Always turns out pretty good.
Something else I was looking for if anyone knows is the weight rating for any roof mounted items. I couldn't find that either. Can you stand on the roof & walk around? I don't think I ever saw anything on that, but was wondering if that was safe.
