I like to leave the side door open as often as I can when I’m camped. Let the outside into the Rolling Steel Tent. But there’s a downside. All that sunlight fades my bedding. And, in the case of my red fitted sheet, it weakened the fibers to the point of shredding.
An awning could alleviate the problem. I have a tarp and some camo netting. But unpacking, setting it up, taking it down and packing it away again is annoying since I move so often. So I’ll just try to park with the side door not facing south whenever I can.
