First of all, I don’t think the rv is getting hot. It’s a 55 gal. diesel pusher and we live in Missouri…it gets cold here too! The problem we’re having with sweating windows is that my husband “fixes” it each time by spraying window cleaner on them (which does work) but then if he doesn’t get to them right away, they start again at some point later on during the day. He thinks this has something to do with our heating vents not being adjusted properly (he says he can feel air coming out of the vent when he checks). Is there anything else that could be causing these problems? Also, what would you recommend for keeping our RV windows from sweating?Thanks!
