Thanks and I have seen the brochure also, its quite informative.
I am from the west coast and just started looking at all fiberglass RV's to target a brand for which I have settled on the Surfside and Trilium as my preferred models and then went down a rabbit hole of research into the history and different layouts... not certain why I found it so interesting but it is a convenient distraction
I am guessing at this point as the details are quite low on Armor Coach Industries other than some '75 surfiside owners have posted that this was on their label with Winnipeg as the location. There is possible other links to Ventura
and Monarch industries that were in Gimli as the Mennonites in the area were are quite likely linked by relatively close bloodlines.
I have some Mennonite in my blood and know of it well as in my area there are a ton of families with close ties in the same small area.
