John knows me so well.
Michelle, I think you meant that most of the Trilliums were manufactured in Markham Ontario.
I see that on your profile, your trailer is listed as 1979. I am fairly sure it is much earlier. Please take a look at the Trillium serial number list and see where yours fits:
Based on the fact that your front window does not open, and your side windows
have two, vs. three panes, I would guess that your trailer was produced before 13-229
Please feel free to post your serial number, or even better, a picture of the data sheet that may be on the inside of your closet door. Though in this vintage of Trilliums, it does not contain much information. Also, please post pictures, both inside and outside of your Trillium. You can post this either in the serial number thread, or any place, like a Registry for your trailer.
The Richmond Hill factory location adds another interesting wrinkle to the Trillium story. For those of you out there with an earlier Trillium, please take a look at the sticker by the door and let us know what it says.
I see that 13-66
Does say Richmond Hill.
