We have a 23' Hybrid with the 13500k a/c. I use two champion 2000 generators with a parallel kit. The a/c starts quite easily and runs like a champ. I also just tested out a Honda 3000 eu on our camper and it handles it as well. Camper is on our property under a shade tree, but it's about 97F this afternoon. The champions generate 3400 watts continuous and the Honda about 2800 watts.
