first commercially available all electric RV

Seems it would be better to have propane for cooking, hot water, and outdoor grill than electric. Just my thought anyway. I do wonder how long they can withstand rainy or cloudy days. Having propane would allow you to stretch the electric power farther. And personally I prefer parking in the shade, and solar pretty much won't allow you to do that. Parking in full sun in the midwest in the middle of summer would put the AC to the test. :)
