Serial numbers on a Trillium

In discussions on another thread there was some confusion about where the serial number for a Trillium is located.
I have maintained that the SN is the one on the plastic sticky label on the back of the closet door.
There is however a plastic medallion riveted just outside the door. It has a number that looks like it could be a serial number.

After checking, the number on my closet door is what is on my registration, minus a zero that is probably a typo. Also the number on my registration doesn't have the dash. I don't really know what the number outside the door represents.

Hi, David

I have one of those medallions, too- but it's not the one I was talking about in the other thread. That's the certification label for code, etc...mine's number CSA 2301351. The other "medallion" could be a later add-on-? The number on it is the one that matches my Title docs, given as the VIN (unhyphenated). I think I told you that there are no papers at all in the closet, so I didn't get anything that looks like those you posted BUT my number is close enough to yours that clearly, VIN and serial mean the same thing.

Mine's 45- 1100758
Yours' 45- 1101043

Those numbers are close enough pattern-wise to suggest to me that the first two digits represent the model (4500)...beyond that it's anyone's guess what the numbers mean. I do think it's safe to assume that they're NOT meant to be read as a whole production-run number since I doubt that there were more than 1.1 million 4500's made!

The first three digits after the "45" match, though...if our trim/layouts etc. match, that could be what they mean. That leaves "1043" , which might be an indicator of units off the production line....

What do you think?

Francesca

Makes sense. Do you have a picture of your medallion? I wonder if your trailer was built for export. The label in my closet has CSA (Canadian Standards Association) all over it, but a trailer built to be exported to the US would have to comply with US standards.

I'll have to look through my files- my camera's on the fritz, but I might have caught it while taking a picture of something else.

There isn't anything with "CSA" on the medallion or anywhere else- interestingly, the medallion you picture and my trailer's "twin" I refer to in line one of my previous post is from "RVIA", which is the "RV Industry of America". So both were "certified" by THAT group, whoever they may have been in 1978!

The funny thing related to your papers is that while they refer to the "CSA" thing on the outside of the trailer, there's nothing on the paper giving a number etc. to look for. What the heck is THAT all about???
Still:
I think that reference is to the "RVIA" medallion- look at our numbers...not that far apart!

I suspect you are correct. Most trailers built in Canada do comply with the US standards as well but they need to have something on them that says that in order to be exported.... goes the same bringing a trailer into Canada. I needed a letter from Scamp that stated it conformed to Canadian Standards as it didnt have any labels or stamps on it already that said that. When I called Scamp they seemed to know what I needed what the wording etc needed to be on the letter so I had no problems.

I'm a bit confused about what you are saying. Our serial numbers are very close. Are you saying that the RVIA medallions are also similar?
The picture of the sticker on the closet door was cut off. Below is the bottom half. Notice the typo on my GVW. 4410 Kg is 9722 lb.

That is exactly what I'm saying- you must have missed it when I said it the first time!

It's the very first line in post number 2 (immediately below your medallion picture), and I give the number, which is within 33 digits of yours!

Your RVIA: 2301318
Mine RVIA: 2301351

Per the rest of the paper, just posted: No "CSA/RVIA/whatever" number match there, either...what the heck???

I do love the tire specs, though...everybody running around on 50 pounds of air should take note if they have complaints about rough ride!

It seems odd that the RVIA numbers would be so close, when the serial numbers are out by 285. Maybe the RVIA approvals were done in batches of 9, all with the same number. Either way, your trailer and mine are kin.

Well, since your trailer's numbers are "earlier" than my trailer's numbers...can it be possible?... after all these many long years?...

OK, I no longer have any guess as to the meaning of the RVIA numbers. Mine is lower then yours, but my serial number is higher. I give up!

O.K.

I'll be the Mom.

OR

We could go by the RVIA number plus just the last two digits of our VIN's, and that would make you the Mom again.

My ownership says I have a '81 4500.

The paper in my trailer's closet says my VIN # is 45 1121733. So using Franseca's logic, 112 could mean the model #. My trailer has a front diner in addition to the large dining table/Bed at the back. The frig model is RM 3607.

The RVIA medallion's # is 2939305.

Hey! We've got a FAMILY, David!
Welcome home, Noreen...you little whippersnapper, you...

Adding you to the family tree, here rearranged low-to-high according to last four digits of VIN...and since I like the way you think, model-wise, I'm assigning a color to the first three digits after "45", which we think might denote a style. Blue is front gaucho and red is front dinette:

Francesca:45- 110 0758...'78: Front Gaucho
David: 45- .....1101043 ...'78Front Gaucho
Noreen:45-... ..1121733...'81: Front Dinette

Now we're gettin' somewhere...if enough prodigals come in from the cold, we might be able to discern a real pattern!

Francesca

P.S.

Hey Noreen- do you have an "RVIA" medallion by your front door, and if so, what's the number?

Thanks!

F.

P.P.S.

We're looking for all other Trillium sizes/models too, folks, so post away!


F.

Noreen, Are you sure it is an RM3607? According to this table, that fridge is 49.5” tall.
Refrigerator Conversion Chart
Your registry is not very informative, I am going to make the standard wish. Pictures please? Especially of the fridge. Front dinette models are rare enough that I don't get to see one very often, and having options on replacement fridges is nice.
Did they figure out how to convert pounds to KG on your GVW? I just realized what the error was. They multiplied by 2.2, instead of dividing. My tug is not rated to pull 4410 KG anyway.
