Bought two 24"x25' rolls of the foil faced thin foam insulation at HD for about $22 apiece. One piece stayed original length, it goes inside the pop-up portion against the canvas and behind the raising bars. I feed it down each side from the back. So it extends from the front of the raising bar on one side, around the back and forward to the front of the raising bar on the other. Cut the other piece at about 18'. It tucks behind the raising bar on one side, goes up front, across the canvas at the end of the bed and back down the other side to tuck behind the other raising bar. Takes about 3-5 minutes to install both sections.
Camped last night in temperatures that got to about 25 degrees. While I have no quantitative data, I think it made a significant difference. Had the furnace set at about 50 degrees and it only came on twice during the night.
When I remove the foil/foam, I fold each piece into a pile equal to the length of the mattress and store them under the mattress.
Looks like an inexpensive and effective improvement to cold weather camping.
Also, with foil all around the inside in place of the canvas, it's really bright at night with the lights on![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Got the idea after seeing a somewhat similar system described on here and and used in a pop up trailer. I've used this foil/foam stuff behind the hot water radiators in my house to reflect the heat into the room.
