I have the same RV and went through several battery over a 1 year period.
I noticed several problems where as one of the house batteries would get hot while on shore power.
I found a lose grounding connection under the bed on the right side, there is a grounding strip with screws in them.
Just make sure there all tight.
Second thing I found is to only use AGM batteries
( comparable to the oem) once I installed these all of the problems I had with the batteries stopped.
Just for your information you have the circuit breaker towards the bottom center of the generator.
next to the house batteries you have a breaker on the upper right wall that when tripped will have a small red arm (flag) that will slide out signaling the unit has tripped ( you can locate this by locating the two red battery cables that are connected to the black breaker)
