Edited to add: Booker, it looks like we were typing at the same time
It looks to me like the corporate headquarters is in the U.S. and the "factory" is in Canada.
As I understand it, they were going to have to fulfill a very expensive number of environmental requirements to manufacture the trailers at a new plant in the US (which would probably have been cost-prohibitive for a new business), and so they contracted with Escape Trailers* in Chilliwack to mold the bodies for them at their existing plant. The address shown for Trillium
RV's "factory address," is, indeed the same exact address that Escape has.
The latter is simply what I understand; the former is shown on the Trillium RV website, as follows:
Corporate Office/Sales//Mailing Address:
Trillium RV Ltd.
1894 Hwy 50 East
Carson City, NV 89701
Phone 775: 443-8946
8945 Ashwell Road
Chilliwack, BC V2P-7E4
*Escape makes their own trailers, which are also based on the 1970's Trillium trailers.
As far as I know, the molding of trailer shells is the only connection Trillium RV has with Escape.
