Bottom line if you want your new camper to stay looking new keep it covered and waxed all the time when not using it. I never had much luck with tarps and or covers they were just too inconvenient and took too long to put on and remove. Tarps and covers large enough are expensive to replace every 2 or 3 years. Also if it was windy while trying to install you may as well forget it. I like to have easy regular access in off season to keep check on things like dampness and to watch for mice intrusion and so on. A couple of mice can ruin a camper in less than a week. Tarps can damage the exterior finish when windy from the constant movement of the material and tie down ropes or straps. IMO a garage or simple dedicated shelter is the best and most cost effective alternative. When you get home just drive in and done, easy dry access to load, unload,and maintain.
