Thank you for that info, mine is #121 model 8TT made in that factory in 1971.
I will file the info in my scrapbook.
The hull in the
Havasu album does not have the corrugated molded in features into the roof and pop top roof our does, these were not added in after the fact when it was molded, when the chop was layered into the mold these features were there, part of that mold...looking closely at the features in our trailer the corrugations were part of the mold itself.
Picture one on the bottom left is a
Campster frame, the prime coated one to the right is the Astro frame with the tongue made longer...but the frame lay out is the same as factory in 1971.
The differences in the two frames are huge.
I would pull sharks teeth to see the frame of the Havasu.
I think it would be interesting to take the obvious improvements in these "boxy design cousins" into account to establish a rough generational order using design improvement criteria as one of the clues to the flow of innovation correlated to date of manufacturer.
I would make great effort to see a gathering of these little guys into one place for comparisons sake, not as squat oddities to be a source of amusement, but as serious camping trailers with a niche of honor.
