Outside in the RV storage lot at the U.S. Air Force Academy.
I don't use a large cover (too windy) but do have a cloth cover over the A/C on the roof and over the tires. Also, a small cover over the electric tongue jack and I put the electrical jack inside when in storage. The trailer has a very large awning and one over the slideout, as well, so I use the pro-tech covers for those to protect from the ultra-high UV rays here at 7,000 feet.
A neighbor got brave and just put a brand-new, huge, cover over his so I'll see how many weeks it lasts!!
