Cover the entire under side of your dash starting at the bottom of the windsheild to the fire wall. Then go down the fire wall and roll it under the RV until you run out of good places to stick the insulation to.

Leave opening for wires / hose to poke though. I take your time, it took me hours to insulate my RV properly and I never regreted it. Use a roller to press the insulation firmly for proper adhesion. I duct taped a two or 3 foot pole to a roller in order to push up/back the insulation where my arms could not ready.

I put one to two layers of Dynomat type down first and one to TWO layers of Fat Mat 3/4 inch foam insulatation. But you will want a minium of one layer of each type.

Thanks so much! I will take a look tomorrow. It sounds a bit daunting. I’m sure every outside project will be easier once we are experiencing our two weeks of Fall weather.
