In the past, the author has reached out to boler owners on several, if not all, major RV trailer groups across North America to poll and survey for the highest known flat top boler unit number currently existing and owned. This was done to test the validity of decades old folktales on the internet claiming that only the first 100 bolers were made with a flat roof. The same test was made to determine the validity of the folktale that the first 40 bolers were recalled to fit them with ensolite insulation. The results (below) are samples from our recent research findings that show notable contradictions to both these old internet folktales and show them to be less than reputable accounts of boler history.
You can be the judge.
