Heating system lack of air flow

[huntindog]

Thanks for this detail...much appreciated. - the 12v heat pads are another option I was considering. May I ask what model you installed the above on? I have a 21' XLS 17MKE and I may be limited for space and weight of the polyisocronate insulation boards...Thankfully I live in North Texas and the lowest I've seen was a freakish 1F a couple of years ago!

I installed the polyisocronate om my Palominio Sabre 30BHDS, and on my present momentum. I comes in different thicknesses from 1/2" to 2" I used mostly 1". In some places it was easier to the several layers of the thinner 1/2". This is a totally custom project as no two coaches are the same.
