So using an automotive charger to charge the two batteries at the same time is no issue? Connected to positive on one battery and negative on the other, of course.

Not quite. If you are using two 12 volt batteries you can connect one to the camper and the other to the charger alternating as required. If you choose to use two 12 volt batteries at the same time they must be connected in parallel. That is connect positive to positive and negative to negative on the batteries and either positive to camper positive and either negative to camper negative. With the batteries connected as above you can connect a stand alone charger by connecting its positive to either battery positive and its negative to either battery negative.

For balanced charging of paralleled batteries you want to connect the positive and negative charger leads to opposite batteries and not both on the same battery. I think that’s what the poster above was suggesting.

Somewhat related, my owners manual says not to operate slide without a battery.

Thanks 6.2! Seems a high draw could totally cause an issue.
I got my converter today and BONUS! I got a 4 stage 75 amp power max instead of what I ordered (3 stage 55 amp) [emoticon]
I'll take the upgrade.
I will eventually install larger gauge charging wires, once I pull the ramset fasteners off the belly. Haven't figured out an easy way to get them out. I'll just replace with self taping screws once I decide to tackle that project.
I'll keep you all posted.
Thanks Scott
