A "practical consideration" that just occurred to me is mobility during storage. If you're in a commercial storage yard, they may have specific rules concerning storage with landing gear or stabilizers down. Check with the storage site management for any rules.
If you're storing on your own property and plan to remove your batteries, remember that you'll have to reintall the batteries to move the trailer (even in the event of an emergency), so if you're taking the batteries out, essentially you're "immobilizing your RV" if you store it with the stabilizers down or with a leveling system in use. It may not matter, then again, "what if's" happen all the time. For instance, what if there's a fire in the garage and your RV is parked next to it. What if there's a reason to move it to access something else, like a fallen tree or a branch on the shed behind it. There's lots more, so "permanently immobilizing" an RV by putting down stabilizers or leveling system jacks and removing the batteries may not be the best storage condition.
