House Battery Charge While Underway
Once again I come to the best wisdom source to be found. 07 Holiday Rambler, 4 6v house batts, Magnum controller, Magnum inverter 2012. Situation is, when we dry camp we run the gen for 2 hours...

You probably have a BIRD device not doing its job. Bi directional Relay Delay.
Look inside your battery compartment and see if there is a large solenoid mounted on the back wall. Be careful because the thing can get very hot to the touch if plugged into shoreline, generator running, or the engine running for several hours.
The solenoid would have large battery cables on each side of it and two small wires. One may be violet.
Plug into shoreline, start the generator OR start the engine. Do not run the generator and the engine at the same time because there may be a defeat function under those conditions.
Now use a 12 volt test light or a meter to see what is happening on the violet wire. It should light the test light and show 13.5 volts or more. If it does, you need to measure the voltage on each side of the solenoid where the large wires are. IF the voltage is not exactly the same, the solenoid needs to be taken apart and repaired or just replace it with one with silver contacts.
If you get this far I can steer you to the right part number and supplier.
