Closed cell Foam on Bed

Very happy with a 1-1/2" foam pad under my Lance 851, no compression and no movement of any kind. Foam comes in different compressive strengths. Foamular 1000 is good for 100 PSI or about 460,000 pounds for a 4x8 sheet. A good way to save over 100 lbs vs plywood.

Thanks , I actually have bought 2 , I believe they are also 1&1/2" foam pink sheets , not sure if they are the 1000 or not . I only have a Starcraft pop up pu camper so the weight is no where near what you guys with the lances have. Mine may bounce a bit more, but I am not doing any off road or long trips with it either. Anymore thoughts out there? Life is Good!
