Clyde, I did the pipe insulation we we first bought the MH but their basement heat is a little weak the coach is always warm at any temp. but the basement cools off real quick. I used the sheet insulation on the doors of my old pace and it made a big difference but we still had elec. heat to back us up. I guess more insulation in those compartments won't hurt still have a few more weeks to do something!!!
