The dealership where we purchased our new Durango 5th wheel always equips all new trailers with two batteries and two full propane tanks at delivery. This is the way they installed the two batteries. While I can appreciate their adding two batteries instead of the typical one, and I understand them using cheap lead-acid batteries, and I like that they actually paralleled the batteries correctly, with positives hooked from battery A to battery B then to trailer input, and negatives from battery B to battery A then to trailer input, keeping all paths equidistance to/from batteries, I wasn't impressed with the 10ga wire they used to jumper between batteries. I tried to explain to the service department person who did my PDI walkthrough that these needed to be the same gauge wire as the leads from there to the inverter in order to properly carry the load of the inverter running off the batteries. He just didn't get it, so I accepted the trailer and will swap out the paralleling cables with 4ga this week. Attachments:

The connecting cables should always be equal or greater gauge than those going to the converter. Jay |

Thanks for sharing this detail, I wasn't aware of that.
"actually paralleled the batteries correctly, with positives hooked from battery A to battery B then to trailer input, and negatives from battery B to battery A then to trailer input, keeping all paths equidistance to/from batteries"
I'll remember now if/when I upgrade.

They'll learn the hard way when someone loses their rig in a fire and the insurance adjuster finds the inadequate wiring used. Their insurance will pay out, not the owner's =and= the owner will likely sue them on top. I sure would.
