Courtney,

After thinking about how the isolator is set up (it is actually a bigdiode),
you are absolutely correct that I will be potentially draining boththe vans
main and deep cycle batteries so in retrospect this would not be agood idea.

I guess that I can connect to the auxiliary (deep cycle) battery terminalbut
am still concerned about the mismatch with the trailer batteries. Isuppose
ann ideal situation would be to use a three battery isolator but Iam not
excited about spending another hundred and some dollars on a largeenough
3-battery isolator (I presently have a 165 A isolator), particularlysince the
present isolator is working well after having problems with smallerversions.
