Insulation in Under Belly

Section of under belly removed for a repair. I am considering adding 1 inch styrofoam insulation below the the tanks. This material would be above and lay on the belly material. I would like to hear from members who have experience in providing a warmer living experience.

I put an extra inch of Styrofoam under mine. I don't know if it helped but it can't hurt. I had one of the panels in the back off and I slid a sheet in it went so I slid another one in then another until I had it all the way to the front of the main body of the camper. It got tight and I had to take a panel or 2 lose on one side but it went.

I don't know if your Mountaineer is built the same as my Montana, but here's what I did to make the fiver a lot less drafty.

There was a very noticable difference both winter and summer.

I worked camped in ours three different winters saw temp. to -8. I added what you would use to wrap duct work it's 1.5" thick and has foil on one side with thread running through it for support. The thing that you need to do is cover the trailer frame, the 10" I-beam offers 0 R-value and of course runs the length of the camper. With the insulation I made a bulkhead just behind the gray tank to hold the heat from the heater vent around the three holding tanks. I never had a tank freeze! The fresh water tank has a heating pad applied to the bottom of the tank. All water lines are wrapped and heat taped. Now I'm retired and won't ever stay in that cold weather again so you need to come to some kind of a balance for your needs.

Remember, you don't want to add so much thickness to the insulation as to stop the air flow from your furnace. That's what keeps the pipes and water lines from freezing.

Good advice! Additionally, be sure to RUN the furnace! We set ours to operate around 60° F.
