If I could do it over I would opt for 3000 watt inverter, but that's due to running the AC on battery. When you do the installation be sure to make it easy to access the readout as well as the connections and plugs. Mine is under the dinette seat closest to the larder and I have to put my head into the seat well to read it. I agree with Steve that there are several parts and a change in wiring that make it work so a trip to AM solar may be good if you are camping in the Northwest.
Our inverter has become an essential part of camping and allows us to use an induction cooktop, toaster oven, microwave, 110v lamp, cube heater, and AC. Would not want to be without it.
