For those of us running a roof top tent full time and that is not garage kept, how has the cover for your RTT been holding up in the sun? I'm concerned that the black vinyl cover is going to fade and/or get brittle in a short period of time. I'm also a little concerned with heat being that I've added the LEDs to the inside of the tent with cabling and when sitting packed in the summer sun, it can get toasty. It also doesn't help that my Jeep is solid black. Any words of wisdom for preventative maintenance?
