A friend of mine is a street rodder and he also has reported on the popularity of moulded trailers with that crowd; Doug Mager has also mentioned it here. With the street rod / hot rod community much stronger in British Columbia than the Calgary area, the move by Boler
Works to BC fits well with that likely market.
By the way, my friend is a build-it-yourself custom car enthusiast, not the write-a-check type. Both make valuable contributions to the field, just as both do-it-yourselfers and Boler
Works can contribute in trailers.
