Thanks Bill. I'm right now thinking to re-do the wire from the panel to battery that is up front, with #8 or 6.

Maybe adding a junction box under the camper right below the fridge and splicing in the battery charge wires from the 7 pin to to the new wire to shorten the path to the battery?

I'm also thinking I will take wire for the breakaway brake switch off the panel and through a fuse directly connect to the positive side of the battery. This way the breakaway is always powered, even if I switch off the battery switch and forget to switch it back on.
