I would think 1" thick cardboard would hold up well. It may even have a little more flex to it and that should help stop it from buckling under heavy winds. I haven't tested any of this at all. I'm just reasoning.
Don't use RMAX if you can help it. I ran some fire tests and it the results were scary. I also found that the 6" tape increases the fire risk, so be sure to cover it in foil tape if you can. One more tip: Playa dust makes tape fail to stick. The playa is windy. built it at night under work lights if you can. The cool nights are usually calm and less dusty than the daytime. The morning and evenings are the worst for dust storms. The air heats and cools unevenly and very quickly, causing some crazy winds. Bring extra tape. Have fun on the playa this year!
