The reason we had the underside of the trailer sprayed with foam insulation is primarily to protect the fiberglass from rock chips. We drive plenty on logging roads.
I'd prefer not to fix rock chips anywhere but especially the trailer bottom.
Of course, this insulation will make it more work, if I have to repair anything on the underside.
And the added bonus is the floor seems warmer.
