I would guess a few other members including myself are out working on some of your tips as they are quite good and appreciated.
I am particularly interested in your bathroom sky light mod and if you have some pics that would be helpful. I have a piece of foil backed foam board I use there now, but it cuts down on the light a good bit in the bathroom. If the window tint works good without knocking a good bit of the light out, I would go for that mod
I also checked the AC thermistor and found that mine was already about 4" inches up from the frame. Have never had any problem keeping coach cooled so far except when my transfer switch decided to melt down a year or so ago.
I probably should not have said that.
Anyway, thanks for posting the tips as that is what this forum is all about passing along helpful info.
