Well - all points well taken!  I shouldn't have said
"best", rather "this has worked for me for 10 years
with no problem".  I don't have a westy so my
situation may be slightly different.  My Dometic
fridge is only a 2-way, must be isolated from the main
battery for obvious reasons, so needs the aux. battery
to be charged unless I'm at at KOA or something with a
110v hookup.  I didn't know about the separators but
they sound good too.  The isolator has been convenient
and reliable for me, and my fridge seems to remain
cold as long as I drive every couple of days.
