"....it was stored on wood blocks with water jugs inside to keep the wood interior in good condition~~"

I just read this on another forum and have never heard anything like it before...any comments??

Although we don't put ours up on blocks, as AZ is very dry, we have followed the recommendation to store jugs of H2O in the coach in an attempt to maintain some humidity. Whether this is a realistic activity I have not spent the time to calculate (fudge) an estimate.
I have not seen any other coach on blocks or on jacks during storage in the RV storage location in Peoria. We do park on plywood and cover the tires.

I have not heard anything about placing water jugs inside of a motorhome. I live in Florida and I would say the humidity here takes care of the water jug idea.

I have heard if you store your motorhome the jacks should be down or the motorhome should be supported on blocks. This prevents flat spots on the tires and prevents sidewall damage.

I have also been told if you remove your batteries they should never be placed on a bare concrete floor and should be on wood blocks or thick plywood.

In AZ I think the humidity is occasionally as high as 40%.
