OK, thank you for your response. We want to power the front and back tvs, the dish reciever (tailgater), and a dvd player, and charge our computer and cells. Not all at once! Just do not like the generator running when we are viewing the tube. We camp off the grid for about 2 months every winter, (7 days out, 2 days in). I think a 1000 watt would be adequate, placed along side the house batteries, and we understand it will tie into the two separate outlets for the two tvs.
My concern is the ease of which it turns off when you go to shore power. The Xantrex true sine has a remote panel you turn on and off. The sunforce doesn't. Also the Xantrex has an add on unit ($62) to make the shore power to inverter power automatic. I just don't know if it is necessary.
And is a solar panel a good idea? How much generator time would it save? We are in a lot of sun during our trips. I guess one step at a time.
