so i finally got the time to do a spreadsheet of the electronics I'd sometimes need to have in the van, and running on 120v.
it is just below 2,100 watts.... (max) all on an inverter.... and that is not including the 12v lights, ceiling fan, etc in the van.
I really dont want to haul a generator
So... pardon the novice questions:
would a 2,800 watt inverter be enough?
and how much battery capacity would I want to be able to run this gear (just less than 2,100 watts) for, say, 1 hour? (3 hour?)
how much solar would anyone suggest for the roof to be able to more or less recharge in about a day.... yes I know time of year / angle of sun all is a variable.
Thanks for any and all tips and thoughts.

A single gp31 is only in the 120ah range, so the 2000 to 2800 watt inverter would really only be able to run with the engine on, and only if the wiring is large enough to supply 100 amp to the coach. The Isotherm will likely use 30-70ah of battery per day, leaving little for anything else.
I thing you will need more battery, at least double, probably the more common two 6 volt golf cart batteries that are in the 220ah range. You need to be able to recharge them reliably so that is part of the use pattern and equipment, so shore charger if you often plug in, solar for at least some of the recharge capacity, and some sort of generator for the rest if the others can't keep up.
