Winter RV camping

Flyingdog I was reading this forum regarding the winter camping and came across your Solar coverings for windows made from spray painting cardboard in the cooler climates. I just have one question about how you get the 1" clearance between the window and the cardboard. Can I ask you maintained this?

My RV window glass is set in about 1" from the walls already, so just putting cardboard flush with the walls works well enough in my case. It doesn't need to be exact or anything. Basically, the space just needs to be big enough, about 1" to 1.5", that passive circulation can set up as the air heats and rises through the space. If it's too small of a space, a lot of the heat could radiate out through the window glass instead of heating your camper...though too much wouldn't heat the air very well.

I'm in the process of posting some details on my solar heating projects over the years to my blog:
Simple Solar Heating for RVs

I'll post more in the future as I find time
