I think all trailers with powered tongue jack and stabilizers should have a switch on the inside to disable functions after set up to keep accidents or possible damage from happening. Seems like a safety issue to me. You should not have worry about that, but in todays world (especially unsupervised kids)
anything is possible! Also same for outside radio with external controls. A nice feature until you come back to a party in your spot and your speakers are blown out or the batteries are dead !
If you build it they will come!
