Funny thing about these inverter generators, the signal coming out of the power source is AC, it then gets converted to DC, then back to AC.
Why? This way you can run the generator at any RPM. The AC coming out is variable in the frequency, typically fairly high. Often the same speed as the RPM. (i.e., 900 RPM = 900 Hz).
They convert that to a DC signal, and then back to a AC through the inverter. Inverter puts out a steady 50/60hz signal. often a modified square wave.
Anyway, if it were me and I planned on camping a lot, I'd probably get two, but I'd get the 3000watt and then get a smaller one, like a 1000 (or 2000). Run the smaller one when you don't need AC. It can charge the batteries and run all the lights just fine. It is smaller, easier to handle and can last up to 14 hours on a tank of gas. Run the 3000 watt only when you need AC or run the Microwave.
Hassling with a Y cable and having two generators running just seems like too much.
