The roof AC has to be 10 amps at 120 volts. Ask Roadtrek how long they can run the AC in the e-trek. They have 800AH of 12v battery power, and despite initial big claims, now most are saying they can run air maybe 4-5 hours. They also have solar and a 3500+ watt engine generator.
You don't need to have the engine power changed to AC, and then back again to charge the batteries, it will do it directly, and if you want to get the good 3 step charging, you can get a 12v to 12v multistep charger from folks like Sterling.
The frig will probably use in the range of 30 to 60 AH per day, so if you want to stay in the 50% discharge range, it alone would get you to charge point in two days.
Personally, I would chose a Sterling charger over the Powermax, but Powermax isn't bad either.
