I am interested in a cyclone 2812 rv toyhauler. My question is since I have to order one why can't the service be 50 amp from the factory instead of the 30 amp? Since it has to be built, and a 15,000 BTU w/heat pump is offered as an option as well as a 13,500 in the bedroom how will I be able to run both on a 30amp service? It makes no sense to me to offer these options with only a 30amp service and a 4000 generator as the only power available. Should'nt a 50amp service as well as a 5.5 generator be available so one can run the a/c and micro or water heater at the same time?
