I own 2 campers with Atwood jacks.
Atwood jack are activated by time switch that turns off after a minute or 2.
But all remotes operate on the same frequency and if you have your jacks activated and your neighbor operates his remote at the same time - your jacks will respond to neighbor remote.
I had my 2 campers sitting in different corners on my driveway when I work on them and would I not make a habit to make front front support when I drop them, I very likely would end with tipped over camper.
At 2.5-3 tons supported by "toothpick" jacks it doesn't take much.
