For those that know, I don't have a PU yet, working a trade for some work for a mid 90s Coleman PU. Now aside from the simplifying camp setup vs. tent camping, and a more comfortable bed, my primary reason for going with a PU is air conditioning. Yes I can, and DO use AC in my tent via a custom AC port I had my neighborhood tailor install years ago. Unlike a tent though, a Pop up can close off entirely, including the bug screening, to keep sand from blowing through. However camping on the beach, in Texas, in July and campers get HOT, in a hurry, and the AC becomes overwhelmed... With my tent, I set up the tent without the rainfly, toss a sized to fit the tent (via me with scissors and gorilla tape) silver tarp backed with reflectix, over the tent body, including blocking off the bug screen. Not worried about moisture as the AC pulls it out of the air... Anyway, I was wondering, is this something that would work on the canvas parts of a pop up, and how could I go about attaching them? Has anyone else done this and has it worked well enough to keep the pop up comfortable?
