Need check list for Arizona storage

We are full time Arizona residents and have a travel trailer. When we store it between trips we close it up. No vents or windows open. We turn everything off, remove the batteries and place a battery tender on each battery to maintain their charge. We are not hooked up to power so no A/C. We clean the refrigerator, turn it off, and leave the doors open a little just to keep it dry so no mold grows inside. We cover the tires and put the stabilizer jacks down. We also put that aluminum waffle like insulation sheet over each window to keep the sun out. One thing we have noticed is that no matter what we do the plastic parts inside and out will fade and change colors from white to an off yellow creamy color. We cover the awning with a sunshield otherwise the sun will fade and and eventually cause it to deteriorate. Every several months I climb up on the roof and check all the sealant for cracks if I find any I put on new sealant. It ma seem like a lot but not really. We have been RVing for many years and have lived in Arizona for over 40 years. Good luck and welcome to the desert. You will love it. You never have to shovel sunshine.
