I have been tripping the breaker for 3 years since my use/store switch has never worked since I bought the Axis used. I too am concerned about whether the breaker will stand up to this type use long-term.
If I put in a battery disconnect switch, what gauge wires are the batteries using since I will need to get some more?
I also am thinking about putting in a two-battery switch so I can isolate one of the batteries if it goes bad on a trip.
I have quite a bit of room even with two batteries.
The clips are from the dual battery tender that I keep on both the coach and chassis batteries.
