Newell puts in a 1500 watt 120vac + a 4500 watt 220vac elements so you have enough hot water and coach heat on electric for temperatures down in the 20's. But you can only run either electric aqua hot or A/C's due to the high amp draw.
There is a way to add a switch so you can run only the 120vac element and your A/C's at the same time. Rudy Leggett (Trainer) explained it to me and I may add the switch.
If you're going to the rally in June Rudy will be there.
