My vote would be to try the SeaFoam first. I had the exact same issue last fall when I bought my coach. Last month prior to leaving on our current trip I added 2 ounces per gallon of gas in my tank and then drove about 2 miles to make sure it was mixed. The week before our trip I logged several hours on my generator with at least half a load.
I had to buy a ton of Sea Foam because I store with 3/4 of a tank of gas. But even though I burned most of it up the first day on the road I figure my V-10 injectors got cleaned out good also. I know I got almost 1mpg more that first day.
Anyway, it was certainly worth it to spend the money on 8 or 9 cans of SeaFoam because now my gen set runs like a champ going down the road.
