i use this cover for a year now:
https://www.amazon.com/Camco-45761-ULTRAGuard-Pop-Up-Camper/dp/B001IZKDZS
Got it for $75 at walmart.
It has worked very well. Way better than every tarp solution I experimented with.
HOWEVER, get some gorilla tape or similar and stick it over every sharp corner/edge you find on your camper first.
