Just completed a 6000 mile trip and here's a follow-up on the Champion 3100i. First, it only provides 25 amps, with a few amps lost while running through 30 ~ 40 feet of cable. For the 15k AC to run, EVERYTHING had to be off; water heater (sometimes we forgot), fridge (switch to gas), and no other appliance could be used. The converter/charger pulled 8 amps, and with the 15 from the ac, the gen was maxed out. Sometimes it would run great for about 5-10 minutes and then quit, just like it ran out of gas, but it would have a full tank. This continued for about 3 weeks, and then a search revealed others having the same problems. To fix it, I "T'd" into the fuel line to add an external tank and installed an inline, 12v, fuel pump. I ordered what I needed from Amazon, and had it delivered ahead to our next stop. I fabricated a power source for the pump by using a cigarette lighter plug, and plugged it into the generator; it provided power only when running. The difference was amazing; it ran smoother, quieter, stronger. I believe there is a delivery problem with the gravity fed carb. Anyway, worked great the last 2 weeks.
