Doesn’t matter about any powered anti-snake device. Normally those 2 power supplies run the Caravan fridge continuously and charge the Caravan leisure battery when the engine is running, when the caravan is Hooked upto the vehicle.
Anyway, any Electric anti-snake device is normally powered from the caravan 12v leisure system which is continuously charged by the towing vehicle. So for short trips you don't need the towing vehicle 12v supply for the system to work correctly as long as the Caravan leisure battery is fully charged.
Thank you Paul.
To be honest I've never had cause to investigate and I doubt I have the technical competence to anyway.
As long as when I hitch up all the indicators work, the fridge is cold at the end of the trip and the battery shows full charge I have been happy.
I'm now vaguely intrigued by electric anti-snake and wondering if what I pick up tomorrow will have such a device fitted.
