Basement storage is a luxury whether it is your house or your RV. When in doubt store it in the basement. In a house you really only have to worry about the leaning tower of cardboard boxes holding your third grade art projects falling over and trapping the cat. In the RV environment how you store your items can create leveling issues. A house has a solid foundation, but an RV has suspension and if you overload one corner your entire rig may lean that way. Enter the air suspension ride height valve.
