Thanks for the great feedback everyone! The more I think about it, a manual switching system may be best for my usage. I think I would actually prefer not to have an auto switchover to inverter if shore power is lost. If I have hookups, I'll have the refer on auto/electric and possibly the water heater on electric. I would not like these appliances to start using battery power just because I lost power at the pedestal. I would rather be aware and in control of the switchover to inverter so I can adjust the loads accordingly. And if I'm dry camping (which is going to 99.99% of the use case for the inverter), it becomes a straightforward switch setting during setup.
