John,
I just finished this fight and won.
The coach was born with an old constant voltage charger. I replaced that with a PD 9145 with Charge Wizard and that was good, but the batteries were 18 feet from it and it took forever to recharge (lots of generator time).
The wire sized needed to cut the loss to reasonable was a fortune and then I would still have to weave it into the coach structure. So, I ran an new power lead to near the house bank and put a brand new PD9260 about three cable feet away from the bank.
Now I can recharge those babies..... (Data the result of actual experience.)
