Wallyworld camping section - buy a sleeping bag foam bedroll (to lay on ground then put sleepingbag on)I think I paid $7. You can cut 8 or so outta it. Works great.

I say foamboard insulation would work good but will crack if you bend it too far. maybe if you have some thin extra plywood, you could glue it to the bottom so it won't bend.
One of Americas biggest faults is that most would rather shell out hard-earned cash for an inferior no-doubt made in China product instead of making a better product themselves. Make it yerself when ya can. BETTER n CHEAPER. I speak , not so much of the hole covers , but everything in general!
Or buy good 'ole "Made in USA"
