1985 southwind multi battery set up?

A bi-directional 200-amp battery combiner has a lot going for it mainly the ability to manage automatically, "If one battery charges, they all charge". Takes care of storage issues. The ford-type intermittent duty solenoid likewise is a godsend for cross-jumping to allow a high degree of confidence to get -something- started, the generator and converter or engine and alternator. I will never go back to rectifier based isolators as most have damned poor quality 1/2" press fit rectifiers. I don't like playing games when something does not start. Running switches with thirty feet of wire in my book is a loser. So is running cables hither and yon to connect to a rectifier based isolator. Ever see what a rectifier based isolator does to the -other- bank when the vehicle chassis side rectifier in the isolator fails and keeps insisting that the alternator is actually seeing say 12.1 volts on the voltage regulator sense lead? It isn't pretty. A 17 volt battery acts pretty weird. Get out your "to-order-replacements" clipboard because few goodies in an RV can withstand hyper levels of voltage.

IMHO Rectifier isolators rate right up there with polyglass tires, and shift buttons in the middle of the steering wheel.
