I thought shore power would/should keep both house and chassis batteries charged. Any help is much appreciated.

If you have Ed's manual (if you don't go download it) read the part on the BIRD and Trombetta or BCC depending on what system you have to connect/disconnect the coach and chassis batteries from each other. The system is designed so the generator/shore power charges the chassis battery as well as the coach batteries and the engine alternator charges the coach batteries as well as the chassis battery. Your system is apparently not working as it should. When I purchased my 2016 Axis, mine did not work either. The BIRD in my 2016 Axis was wired incorrectly at the factory. It was a simple fix, but difficult to diagnose. If you read Ed's manual, you will see that th BIRD is designed to open the Trombetta and connect the two battery systems. Apparently yours is not doing that. Could be a bad BIRD, bad Trombetta or miswiring. If you search for oneilkeys and BIRD or Trombetta you probably an find the posts outlining my trials and tribulations in the spring if 2016.
