Can any one shed any light on this for me.
Any and all help appreciated

I have found that A LOT OF PEOPLE, TECHS INCLUDED, simply DO NOT know what is going on with batteries.
It's is a shame that "A PROFESSIONALLY INSTALLED" battery bank is not performing correctly. PROFESSIONALLY being used as sarcasm.
One of a hundred problems may be THE PROBLEM. My gut says find someone who understands the systems in a coach to go through it WITH YOU. While EXPLAINING the whole set up TO YOU, a person like the shop manager, will be actually checking the install and may see a problem that suddenly becomes obvious. . Either, the batteries are not taking and holding a charge,. OR they are not correctly installed, OR in the process, SOMEONE, you or them has introduced a new problem in to the formula. A short somewhere? I have a DC clamp meter that can immediately show how big the load is when you start turning things on. First check install. They should be, if 12 volt batteries all be in parallel. + To + and then to the + lead front the coach and - to - then to the frame. Ought to be a total battery disconnect switch on one side or the other. Once you ARE SURE that nothing is wired wrong/backwards or whatever, then disconnect the whole bank and charge it with an external high quality battery charger. Then after 24 hours or more on a charger try putting one thing at a time on line. With a clamp meter or the like, you should be able to see first NO DRAW then a couple amps ambient draw for things like the propane detector and CO detector which are usually ON at all times the batteries are on line. Then start turning things on and watch the draw.
My rule is look at the last "WORK" done, or in other words , every thing the last guy shoulda touched or mighta touched. Good batteries go bad over time, especially with the abuse/extreme load of a residential frig. But system not performing at all well on new batteries, screams SOME BODY SCREWED UP.
Good luck.
