I had a conversation with a Lippert Tech rep on a different issue. But, I did ask him if I could use a Level-Up to lift the RV to remove a tire. His answer was not only no, but heck no. He did not say why, but I suspect the reason was not the capability of the level-up to lift the RV, but the safety of procedure.
I have not had to change a tire yet and hopefully, never will have to. I do carry a suitable bottle jack with me on my travels.
