Hi Dennis.
I realized after posting, that in fact I could bypass the relay and
hook element connections, using fridge switch, ( or as you suggest a
SPDT switch) to the 12V supply.
I do have a second (aux) battery and should have mentioned that.
Given my nature to err on the side of caution, I thought I'd get in
the habit of driving with fridge on 12V instead of LP.
To be clear, I posted this as a solution for those that may want to
drive with fridge on 12V setting, have the older style fridge with
relay on fridge itself, AND have an Aux battery.
Thanks for suggestion and for making those points clear!
Neil.
