I bought a Harbor Freight 2000 generator 2 years ago, and it was just adequate. When the AC compressor came on, the overload LED lit up and it took about 3 seconds for the compressor to come up to speed. Would have to switch off the ECO when AC first turned on. Cost is usually $449 up to $499.
Sam's Club had the A1 Power 2300 watt generator on special for $349. Bought it, let it break in and then plugged the Casita in. Left the ECO switch on. Placed the generator within view from inside the trailer. Turned on the AC, it kicked right on as if it were plugged into house outlet. Motor sped up quick enough so the voltage never dropped.
A lot of attention to RV use were evident. A 30 amp adapter to twist lock, oil funnel, telescoping handle and rear wheels came with it. The pull start handle is on top so the leverage is better if the generator is on the ground. If on the tailgate, not so easy. Bought the 3 year service policy for $50, hope that works out ok.
Weights: A1 Power: 51 lbs. Predator 2000: 47lbs. I'll put up with the extra 4 lbs. With the wheels I can roll it on a piece of plywood from the bench onto the tailgate. Neither one of these is a one hand lift.
