Leaving RV in AZ in summer?

Our block & mortar home is in AZ but we do have a Motorhome. The sun is brutal; any RV left out in the summer sun has faded skin & peeling decals. Our MH is in a closed garage. Even then you have to place buckets or pans of water inside during Apr, May & June until monsoon season starts to keep the wood, fabric & glue from drying out. When monsoon season starts then it is the opposite problem, too much moisture. Even inside the garage we run the AC a small amount to keep mold from growing. A tough environment for leaving a RV unattended. We have friends from Idaho who leave their Air Stream year-round in a nearby park. Skin is fine but I attend to the buckets of water & AC all summer long until they return in Nov. Even then the heat on the roof caused the glue holding the ceiling cover / headliner to let go and drop. This was from heat softening the glue, not from drying out. Tires must be covered or dry rot will occur quickly. We do get more rain during the monsoon season compared to Yuma so your site of choice maybe a little different.
