We hope to be able to do some colder weather camping and I was thinking about how to maximize the thermal efficiency of our camper.
One of the things I realized is that there doesn't appear to be any insulation on/under the floor... so I decided to add some. First, I looked under the camper and realized that the underside of the rig has firing strips running the length of the camper. In my case they are 1 1/2" thick. I decided to install solid rigid foam board to fill the gaps between the runners and bought a sheet of Styrofoam insulation..

I then measured the distance between the runners and ripped the board on my table saw..NOTE the distances between the runners were all different....Measure twice-cut once!
I attached the foam board to the bottom of the camper with the appropriate foam board adhesive by applying the foam to the board and then lowering the camper onto the precisely placed foam boards. I'm letting them sit overnight to bond completely and I should be good to go.
The whole project cost less than $30 and only took an hour. The foam board is impervious to moisture and should last as long as the camper. It provides us with an additional R-7.5 and probably weighs less than 5 pounds.
The foam board pieces sit flush with the runners so they don't affect the height of the camper.
