I have a 2018 Thor Siesta Sprinter 24 SS. We have been on the road now for about 5 weeks, and on two occasions, when we took an AirBnB, our house batteries were dead in less than two days. I had the refrigerator running on gas, no lights on, no a/c, no NOTHING.
Am I missing something? I checked if the frig would run if I turned off the shore power switch and it won't. The batteries at this point are 2.5 years old, and I'm thinking about stopping tomorrow and having them checked since we will be visiting someone who can't have the rig in his yard, so our frig will be on gas for 4 days. If necessary, I'll just replace the two house batteries, but my concern is that I'm missing something here, and the documentation that came with this rig is too minimal to provide any assistance.
Thank you in advance.

The first thing to do is test the batteries. There are only three ways to test flooded batteries (non VRLA). Easiest is to spend the buck and buy a battery load tester and see if they can accept a load. The second ways is to pull the batteries and take them to NAPA, Autozone, Advanced Auto, or any other FLAPS and have then load tested. Lastly, you can use a battery hydrometer to check the acid in your batteries. I still use a little 5 colored ball one that I bought 40 years ago. Testing your batteries will help point you toward your problem.
