I ordered a dual-fuel Champion from Costco. Used it on one trip and retirned it. First the charge port broke. I only ran it on propane for about two hours on the trip. I came home. Poured gas in.....The electric start no longer worked. Yes, the battery was fully charged (12.7v). Nothing. It wouldn't start. So, I tried pull starting it on propane. Nothing. An hour of frustration. I have a 16 year old Honda ie2000u. Starts on the first or second pull EVERY time. I took the Champion back and bought Honda eu3000i. I sold my 2000 yesterday to first person to call me. No squabbles about the price. They knew what they were getting....
