I dont think you have a Boler, Boler's had buckets that the lights
fit into. Pics will help. It is probally some variant of the Boler. Is the serial number plate still on the opposite side of the doorside of the trailer mid way down at the belt line? Where in Winnipeg are you I maybe able to come over and help you identify what you have. I am in Winnipeg as well.
Mark the 3rd weekend of August 2013 on your calander for our 4th Annual Manitoba Fiberglass and Vintage Camper Rally
at St Malo. I am working on my new 1971 Boler to have it ready for the Rally
