I just recently purchased my 2nd iGen4500. The first one was for my pull behind camper. It was very quiet, easy to start and ran all night running my AC on 3/4 of tank of gas. I sold my Camper and the buyer purchased the generator with it. So I just purchased a replacement for my new RV.
I borrowed one in the past and it was flawless. When it was time to buy my own this was the first one I thought of. Packed with tons of features and always starts right up.
