There have been pictures posted where foam board deforms in areas of concentrated camper weight but doesn't deform and actually pushes up into less supported areas of the camper bottom.
On the other hand I have not seen any posts about any heavy rubber mats doing any damage. I have used one under all 5 of the TCs we have owned without any problems.
IMHO, if a foam board is used a sheet of plywood over it would be a good idea.
Thanks for the reply. I guess I should have done a search before making my post. I just did, and here is one post that I found:
"I asked this very question of Northern-lite. Here is what I was told: foam has too much give to it and can cause stress on the camper. He told me to use plywood, followed by a 3/8 inch soft rubber mat. I had a foam board, but got rid of it after NL said the preference is plywood. "
I think I will follow NL's recommendation. Better to follow their suggestion, I think, than not follow it and then have problems downs the road.
