Well I think I found my solution. After reading the most recent newsletter from Tiffin, there was an article about a couple that boondocks 300 days a year in their Phaeton DP. The wife works remotely from the RV and, for them to be fully functional and comfortable, they found that a 2000 watt solar panel system takes care of their needs. I found a complete 2300 watt system with panels, batteries and inverter for just under $4000. I think between that and the generator that would work for us.
Thank you everyone for your insight and input.
