LPG question

[Gingernuts]

I have a 2013 possl 2win pvc the gas locker is inside the back doors! If I put my tow bar mounted scooter rack on the back I can’t get in to isolate the gas for ferry crossings without removing the scooter and part of the rack! Is there a technical workaround like a remote tap or something?

You can get electric shut off valves for tanks I've not seen anything for bottles Basildog should know.
