So, I have gizmos on the bunk ends and the slide out. I have reflectix cut for every window except the front "living room" window, but I do mostly keep that curtain shut with the awning up. We went camping this past weekend, and I do believe I met my match. Temps here in Oklahoma were highs of 102 to 106 every day. Ugh! Between the hours of about 12 to 6 we were pretty miserable. Inside temps got up to the low 90s every day. Now, I realize that these are extreme conditions, but in Oklahoma, this is at least one solid month of the summer, sometimes two (with it this hot this early, looks like it will be for two this year) and I don't want to lose my summer camping time. I was analyzing this situation, and was thinking this... The space between the roof and the window where the reflectix goes in is uncovered, and those portions definitely do get hot. So what about altering my gizmo to add end and side panels? Thinking of adding a roof option too, to camp in extreme conditions. What do you think? Would this eliminate my need for reflectix or would I use both to add some insulation other than just reflective?
