Ever been in a green house?
Under the sun, an RV can become unbearable inside within a few hours of sunrise. It can quickly become hotter inside than outside. So hot inside, you have to retreat outside to get away from the heat. Without A/C, forget about sleeping past 9:30 a.m.. Also, the heat coming through a window frame that's in the sun is very surprisingly large. Trying to sleep in beyond 9:30 a.m. with foil-sided bubble-wrap only covering the glass but not the frame, the heat radiating onto my face from the window frame made me curious. I touched it and burnt my finger.
Instead, vents taped shut, taping foil-sided bubble-wrap over windows and window frames and a few inches beyond, with the same treatment for the roof vents = very comfortable morning, staying comfortable enough all day (except for late one afternoon where I resorted to using A/C for 15 minutes). There was still a significant amount of heat conducting through the fame and through the FWBW, but that was greatly reduced by painters tape over top of the frames outside, and that tape covered with the foil tape, then you're comfortable all day.
Cost? A small roll of the FSBW and a roll of painters tape and a roll of foil tape. Cost benefit? Huge. Comfort or the fuel savings from not running generator for A/C. I'm sure the neighbours appreciated that too.
Getting the rest you need, when you need it or want it, to enjoy your burn more?
The dust is merely a bonus, or a cleanup issue. If you're renting an RV, this can be a cost issue, due to cleanup fees.
And no, it takes time for the heat to get in an open door when it's the size of an RV. Never had an issue going in and out, but that was infrequent, not
high traffic from a dozen people sharing an RV.
