I was just under the beast and it looks like I could box off along the frame rails nice and easy with the insulating boards. This will not help 100% with keeping heat in the rv but it will protect all the tanks, lines, mechanics, which is my main concern.
My plan was to heat the underside with 2 small 300watt ceramic heaters to prevent freeze ups.
What ever I do I will post pics and results after the first deep freeze. {I don't believe I just said "deep freeze", in Tenn.!!! {I'm from upstate NY originally}
