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.

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.
