I would like to have a warmer TC floor... any ideas?

Rigid foam board insulation around the side walls where the camper sits between the wheel wells. That will help.

To wrap the campers base:

I have priced LDPE... Low Density Polyethalene 3/4” thick sheets... expensive but smooth, simi rigid and will not absorb water. You can google it.

I prefer the horse pads under the camper... for the 4’ x 6” x 1” I have found them for $36 each and the same ones for more than $50 each
