Prepare your RV for Storage
When ready to rent a space, make sure to take your proof of ownership and insurance, you will need them before signing your lease. If you choose the common area storage, take pictures of your RV and make sure your insurance company covers your RV while in storage. If your insurance policy does not cover theft or damage, you may want to consider buying another policy.
Do not store your RV on grassy surfaces, gravel or dirt, it will only invite pesky creatures to take residence in your home away from home, and remember to keep the area around it clean.
Remove any electronics, liquid, and food.
If storing during winter in cold temperatures, winterize your RV, drain the water heater tank and all water housed and run antifreeze through the entire system, this will prevent them from freezing.
Inspect the battery and disconnect the negative cable on your battery. If your area freezes during the winter, remove your battery entirely and store the battery at room temperature.
Empty the toilet and water heater
Close off the gas tank
Change or top off your oil, radiator, windshield wiper fluid, and brake fluid
If your RV is going to be sitting still for months at a time, consider taking off the tires to prevent flat spots from forming. Set your RV up on jacks or blocks to extend the life of your tires
Get an RV cover to protect your RV from dust, sun damage, hail, and animal debris
Ultimately, what type of storage best suits you will depend on your preferences. If you go RV camping very often, or need immediate access to your RV, home storage may be better. If you take long breaks and only go RV camping a couple of times a year, it may be better to store it. Either way, make sure whatever RV storage unit you choose best suites your needs.
