RV Repair: how to reconnect house and main batteries, coach batteries, southwind

Question
I have a 1992 southwind by Fleetwood. I disconnected  the batteries and forgot how to reinstall them. Help !

Answer
I will assume you are talking about the two coach batteries.
They are hooked parallel.  The positive lead is hooked to the positive side of one of the batteries, the negative lead is hooked to the negative side of the "other" battery.  A jumper is hooked from the REMAINING negative on one battery to the REMAINING positive on the other battery.
