Tarps and pop ups…

I have a huge white tarp that cover my entire trailer down past the wheels in the winter. But it’s a pain in the butt for on and off frequently since it’s so big. I just need the roof covered, not the deck (see pics). I’ve heard so many horror stories about tarps and ruining roofs. I just rebuilt mine last year, so I don’t wanna mess it up. I also don’t want to just sunbake the heck out of it. Is any all white tarp fine? I’ve just heard the colors heat up too much. Thanks for any thoughts or advice!

tldr: winter cover tarp too big. big annoying move much. smaller all white tarp ok for camper? caveman grateful for thoughts/advice
