I like that idea and:

But, the idea was to be able to leave fridge on aux battery during
short shopping stop (or w.h.y.) IF I needed to run on DC. i.e. I was
out of LP or was running on DC while driving.
I may just set it up so both relays trigger via blue wire way as
that's similar to stock. I mean hey; if I'm taking that long shopping
AND running out ot LP, I deserve to have rotten food right?
;^)
So....
This is all looking like a moderated waste of time on my part (except
that I'm learning good stuff from listers) because most of the time I
run the fridge on LP.

Hmmmm.... good to know. I had read on a Westy site to use a 30 Amp HD relay.
As it stands I'll use the 30 amp. If I start blowing the 30 amp fuse
at aux battery I'll know that I might need a larger relay/fuse.
