If you have a single battery I would take it into a local auto parts store and have them test it.
Sounds like it might possibly have a short within the battery.

Agree, probably a bad/weak battery. If it tests bad think about buying a larger group 27 or better yet, group 29 battery. You might need a larger battery box but it will be worth it in long run. You will see battery pricing similar to this
Group 24 - $119
Group 27 - $129
Group 29 - $139
The biggest bang for your $$$ will be the group 29 battery.
The items you are running should not use that much battery.

I'm guessing you have a typical 12 volt RV battery. Fully charged they carry about 12.8 volts. If you have a volt meter, you can easily check each cell to see if you have a problem. Clean the top of the battery off with a rag and remove the two covers. Starting on the positive termanal with the positive lead, put the negative lean in the first cell closest to the positive terminal. You should get about 2 volts. Then just move the negative lead to the next cell, and the positive lead to the first cell, and you should get about 2 volts. Move both leads down one cell at a time. If any check is less than 2 volts, you probably have a dead cell, or nearly dead. And of course, when you remove the covers, and you have a dry cell, well, shame on you....

If understanding to test method correctly, you want him to put his meter test probes into the battery cell's in the acid?? Bad advice if ya ask me......
The OP would be a lot better off to take it and get it load tested, A battery can have a good voltage reading on it till a load is put on it........

I have to agree with this. Load testing is the best approach.

One could test the individual cells with a hydrometer. Yes/No?

YES, best and safest way. Top off with distilled water as required and charge to bring specific gravity back in line.
