My Winnebago does not charge the engine battery from shore power/generator and the engine battery will discharge in about three weeks.
I installed a "Battery Minder Plus" 12 years ago and it has done a good job of keeping the engine battery charged.
See Battery Minder
The previous owner of my Monterey showed me a trick putting a small flat screwdriver under the battery cross-connect switch to keep it engaged will transfer some of the charge going to the house batteries to the chassis battery. I wouldn't leave it like this for long because I'm sure the solenoid connecting the batteries isn't designed for continuous on, but for short periods it should work to charge the chassis batteries.
Actually on most (all?) motor home the solenoid is a continuous duty type.
Besides the dash switch it is also activated by a wire from the RUN terminal on the ignition switch so the house batteries charge from the alternator while driving.
Still like you I don't think I would be comfortable leaving it activated for days on end.
The Battery Minder is a float charger and is designed to be left connected for as long as necessary.
