Is the year of the coach based on the year of the chassis

Common - yes. We have 2010 Vista 32k on a '09 F53 Chassis. Big deal if there was a major change in the chassis - like from 5sp to 6sp auto trans. Or, V10 to V8.

Yes. I was making that point with an example where you got a better alternator.

(It is not so simple to change an alternator in a C, where it is under/behind things crammed in there. Also in another article it came out you have to file away part of the 2G bracket to fit a 3G ISTR.--doesn't matter now , it was just an example.)

Duralast Gold alternator for that 200 dollars plus labor. If an alternator is why you walked away....hhmmm......

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.

The 1991 Fords and earlier had a bad type of alternator that was infamous for catching fire for some unlucky owners. It also has low amps, which hinders "alternator charging" of the House batteries. The 92s got a newer, better, higher amp alternator, so it is important in that case.

(This was all discussed a while ago on Tech Issues with Mex supplying the gory details on the 91's alternator fires.) My 91 has that alternator, but it is doing ok so far. Fingers crossed.

Doesn't matter now of course, but I thought it might be the same thing with new "generation" changes that matter. AFAIK there are some recent changes to alternator regulation that also affect House charging, so people are getting DC-DC chargers. I don't know what chassis years are involved, but it could matter to some buyers perhaps.

Hmmmm, this is the first I've heard of alternator fires being common or infamous. Neither of mine had issues ('79 & '88...oops; '87 :)), and replacing an alternator with a better unit would likely be relatively inexpensive. So I'm not saying that an alternator is not relevant, just that it wouldn't be a "waste of time".

Why is this going on? We all know the model year of the coach most likely not the year of the vin number.

There's nothing misleading about it. I understand your reasoning, but this is not the world of cars/trucks; You are not buying/selling/registering a bare chassis, you are buying/selling/registering a complete RV, and while a major chassis change may very well make a difference, I would suggest no one would actually consider a lesser alternator as "waste of time" on a used RV, as you suggest. The manufacturer's brochure will normally list the basic drivetrain mechanicals that apply to the first units built in that model year, and then there may in fact be upgrades midyear (when the newer chassis begin their trip down the coach assembly line). So you are actually more likely to get better than the brochure lists, but never worse in the case of split year RVs. Doubtful that you would complain about those improvements/upgrades, right?

I live in CA. My last coach was a 1988 Jamboree, built in 1987 on a 1987 Ford Chassis, and that chassis was actually built in late 1986. So was it a 1986, 1987, or 1988? It was correctly registered as a 1988. CA does in fact, follow the Federal guidelines (I'm sure that exceptions occur, but they are the exception, not the rule).

The only hassle is that when purchasing chassis or tune-up parts, you will need to purchase for an earlier model year, particularly if there were changes. I had to remember to buy for a 1987 rather than 1988, as there were significant changes at that time (Carb vs FI, for example). That was indeed a big change, but I bought the rig knowing it was carb.

Keep in mind, if the chassis and coach had to match, there wouldn't be any current model year coaches even available until mid-year:(. You want to purchase a new 2021 RV? You would need to wait till June of 2021.

You sell it based on what the Title says, you purchased it based on what the title says. If the finisher/manufacturer titled the vehicle as a 2001 2003 whatever THAT is the year of the vehicle. period.
Not on what the headlights look like. The seller cannot change what is on the title, the laws concerning this are very clear. And those that wonder why DMV gets confused?

Good day.

Yes, but I meant you don't want to see an ad for an X year C that you know has the new alternator and when you go to look at it, you see it is the previous year's model with the older not so good alternator, so you wasted your time. You think the seller should have said this in his ad.

If the Law says you must call it X year in your ad, then you can still mention the actual chassis year so not to mislead buyers can't you?
