DavidEM: great planning. You’ve put a lot of thought into it
One option that you might enjoy is a 1000-2000 watt inverter.
If you follow the template for the integrated “AIMs Inverter Mod” with auto transfer switch done by many Vegas/Axis owners...it’ll allow you to use your TVs and non-GFI outlets without running the genny
It also allows you to run the fridge off of the inverter while enroute, which saves on propane.
Of course as a DIYer, you may then choose solar, followed by a roof-mount dome dish
