Only drawing power from Chassis battery

UPDATE: Can it be as simple (and dumb) as this?
I just double checked the battery control center under the hood. It LOOKS as though the chassis battery is connected to the coach battery input in the box, and vice versa. Is there any danger to simply swapping them to see if that's the problem?

Here's the short version:
When camping without shore power overnight our chassis battery goes dead. Today I disconnected from shore power, turned on the furnace, and did some tests with my amp clamp.

1) Chassis battery - 0.4 amps
2) House batteries - 0 amps

When I turn off the "main" disconnect relay in the coach the tank sensors go off but all else looks normal.

When I disconnect the "Aux" battery using the disconnect relay in the coach everything in the coach goes off except the tank sensors.

When I physically disconnect my chassis battery everything in the coach goes dead.

When I physically disconnect the house batteries the tank sensors go off but all else stays on.

Where do I check from here?

BACKGROUND
Last year I made a dumb mistake and miswired new house batteries. I discovered the problem within a few minutes but by then it had gotten pretty hot.

The converter failed and I replaced it. It seems to be working fine now.

Shortly after that I discover that the alternator was no longer charging the house batteries. A mobile tech replaced a solenoid in the battery control center and everything seemed to work fine.

The total lack of power being drawn from the house batteries seems to be a new issue.

It sounds like it might be hooked up wrong to me. If you have an explanation as to how that happened than I would do what you're proposing.
Disconnect chassis battery and hook up house batteries to where they're supposed to be. After you're sure the house side of things is good to go than reconnect the chassis b. Take pics first.

What okcnewbie said;
Your house batteries should be powering your lights and appliances in the rig(which you don't tell us what it is) and the chassis battery should be powering the engine. Sounds like it's backwards to me, and that's why the chassis battery is going dead.

Ok. I did what I proposed and swapped the house and chassis wires on the battery control center so that each was connected in the proper place. All seems to be working properly now. Our first full night boondocking will be the test!

As to how it happed - As far as I can tell it must have been the mobile tech. He took out the entire control center for access when replacing the solenoid. He must have just lost focus and connected those two wires to the wrong posts when putting it all back together. Of course everything seemed to work at the time. It took an overnight boondocking to reveal the problem.

Future advice. If and when you get into this kind of situation again(and you will), take as many pictures as you need to ensure you, or someone else, can assemble it properly. You were blessed this time, but the next time you or your tech could cause significant damage to systems.
