Storage/Undercarriage Moisture

[pincherman]

Hi, folks. I wonder if anyone has experience and/or suggestions with
storing your RV over bare earth/sand/dead sod whatever.
I had stored a '93 Class C on a CONCRETE DRIVEWAY for over 20 years and didn't realize how beneficial it was on the undercarriage until I went to sell and had a few people comment how remarkable the underside looked (very little rust and degradation).
I no longer have access to concrete but must use the community RV storage lot (mostly dead sod w/open sand) here in coastal/central FLORIDA.
Question: Can pinning down an 11 MIL TARP directly below the undercarriage of my Class 'A' HELP OR HURT?

Thanks in advance for any input on this!

Moisture evaporates from the ground and condenses on the cooler metal above. The idea of putting down a tarp or some heavy plastic to stop the moisture from coming up towards the cooler metal parts and condensing is a big help.

I put used rubber roofing on the ground under my 5th wheel. It helps considerably.

Brialin...where would one go to find that? That sounds like a solid idea.

The sandy Florida soil doesn't hold moisture at all, so no worries. Won't bther either the chassis or the tires. We've lived in Florida for 43 years and never had ground moisture problems with our boat trailers or RVs. If you are going to have moisture problems in Florida, it will be from the very high humidity, not the soil. Ventilate the RV interior well or leave the a/c on.

If you can't get waste roofing, try a product called Rubberrific and by other names its play ground rubber that you can get at your local Home Depot or Lowes or Ace Hardware. It ain't cheap but but it down thick and it will hold color for about 5 years
