Generator not run, 2019 Winnebago 22C Outlook

[CarnivalWriter]

Greetings All, I'm very close to buying a 2019 Winnebago 22C Outlook with just under 40,000 miles. He wants just under $65K for it. I think that is close to a fair price, with me proposing $63,000 --- based on NADA median price for private sale retail.
That doesn't address two key issues, which leads me here. How to fix, and what will it cost?
1) The generator wasn't started over the course of at least four months, and perhaps longer. He says the generator runs, but that the carburetor is gunked up and has to be serviced. What does this cost? Could it be serious?
2) Apparently the refrigerator is ONLY on electric, no propane hook up. He says there are two, 6 volt batteries, total. This makes no sense to me -- the part about having a refrigerator you can't use if you go off grid for three days -- but more importantly, how to fix? Maybe a roof solar panel and an additional battery?

I wouldn't buy an RV without a gas refrigerator. We do a lot of off grid camping. A generator fuel issue could be a cheap fix or could run into the hundreds. Do you like to gamble?

I think I was in denial that Winnebago would put an electric-only fridge in a 2019 vehicle, and not a dual or whatever. But, like I said, very new to this.

NADA Used Retail with mileage factored in, is $68,773. The 40,000 is actually a 3% deduction. This is with no additions for any optional equipment. It looks like the generator was not standard so that would be an addition. From that the price looks good. Again, no adjustments for condition.
It would seem like the having a working generator would be much better than more batteries. Refrigerators, especially with a freezer, use a lot of electricity.
Let me know if we can help with anything. Rates seem to be holding for now.

Thanks Ken and Sanda,
I just purchased a 2017 Minnie Winnie with less than 10K miles on it for $70K without any of those issues. Much appreciate your feedback with special thanks to Sanda for the bluntness of whether I liked to gamble. See ya'll down the road.
