The house battery voltage should jump a full volt as you start the main engine.
Polarity matters so double check. Plug in the RV and see if the house battery starts charging.
Otherwise for charging en route you need to poke along the charging cable from the battery to the isolator and if needed back to the alternator. Along the way you will find voltage jumps up at some point. You will need to repair, replace, clean, tighten, or adjust the component at that spot. Generally the issue will be at a connection, not mid wire in some blind area.
Good luck. Post what you find.
