Be sure to flush the tanks very thoroughly. Especially the black tank. You want to see clear, clean water draining. Whatever is left will be bone dry and rock hard when you get back in 6 months, or whenever. A friend of mine left his 5’er in open storage for 8 months here during the covid. His dried out black tank residue caused major problems…We purchased a Rv in AZ that we wont be taking back to Wi. It’s a 2021 Keystone Alpine. I’m trying to find a good resource on storing an RV in Extreme heat. I know a cover is probably the first but that is not going to happen This year. Any direction would be appreciated. We are leaving Early April.

We have a house in Bullhead City which gets in the summer well over 110 outside and at least to 100 inside. As a vacation home, we are not there a ton, so the interior gets baked. Of course I do not run the AC when we are not there...If it were me, I'd use a reflective material on the inside of the windows to minimize direct sun heat gain. I would lift the negative cable off of all of the batteries, once they are fully charged. I do prefer to leave vents open some but if you do not have vent covers it might get some rain in the event that should happen. Antifreeze won't prevent evaporation so I would just put the stoppers into the sinks. You may want to fill the toilet bowl with water and cover it with Saran wrap of similar product to minimize evaporation but you won't be able to completely prevent it. I would put a couple of buckets of water inside for moisture. Tire covers to keep the sun off is about all that you can do for that. Protective products are not recommended by tire manufacturers.
There is no single answer that is right or wrong. What I do (retired electromechanical technician) is to make sure that the battery is fully charged and then lift the negative cable. I would then remove all electricity from the RV as that eliminates a lot of potential issues. If I were to be gone for a very long time, then I would connect a trickle charger to the battery, with that negative cable removed. I would supply power to the charger via a separate cord, leaving the RV cord disconnected. By doing this you remove any possible issue from power surges from things like a lightning strike.Do I plug in the camper? Do I disconnect battery to unit and put on a trickle charger?
