Not positive, but I think all electric MHs have been offered for some time now.
We have lots of solar and battery capacity, a residential fridge and one of the 3 A/Cs is also a heat pump. But we still have propane stove/oven, water heater and furnace. While we could manage (even while boondocking) without propane, I really wouldn't want to. By the way, we are full-timers, so we have to think about all 4 seasons when it comes to heating and cooling.
A lot of this can be blamed on the push to eliminate fossil fuels which is ridiculous to begin with.
