According to that, the 3G came out in the 94s, not the 92s like I said. So that means you could not spot a 92 by its headlight shape, etc and know it has a 3G. If the 94 C has a 93 chassis with a 2G, that would be a problem for me, but it is all history now.
I do imagine the same sort of thing can be happening with more recent model years.
Interesting article, but I do see that it is pretty simple to change out the 1G/2G alternator with a 3G, so the idea that the alternator would be the deciding factor in whether or not to purchase a particular RV is unlikely, at least from my perspective, although yours may be different. I also see nothing in the article (other than the one picture caption) mentioning fires. If it was common or "infamous", as you suggest, I'd expect the article itself would mention it in the text.
