Is the trailer from Canada? If so, "Holiday" Trailers were originally built near or in Kitchener Ontario. The company was called Holiday Trailers and operated from the early 1960's until they were purchased by Norcom Leisure Products Ltd. which operated two plants from the mid 1970's to 1981 / 1982. The one plant was in Kitchener and they had a second plant near St. Julie Quebec on the east side of Montreal off Hwy 20. The Kitchener plant supplied Ontario and Western Canada and the Quebec Plant supplied Eastern Canada. When Norcom purchased the company they began producing Holiday Class C motor homes, fifth wheels, park models and travel trailers. The 1981/1982 recession killed them as demand dropped due to 21% interest rates and quality issues as they began to cut quality and corners to save money. To this day their products produced in the late 70's and early 80's can be seen on the highways and in campgrounds that allow older units. The units featured the name holiday as a wave (sea-wave shape)and the common orange / yellow stripes for this era. I worked for an RV dealer in Sarnia , Ontario that sold this line for a few years until they went bankrupt.
