Just as a side note mchurch314...I have a 3791RD also. I just ordered a disconnect for the battery box which I put on the negative side. It's a knife style switch so it's easy to use and see if it's connected. Cost about $8 on Amazon. The red handled disconnect will still allow things to run, and has no effect on the fridge which has its own disconnect in the front.
