Hi Mark,
So its definitely not a Hi-Lo! That sure explains some the inconsistencies, like both halves of the door opening outward, the black roof-line trim, etc.
Like Bob, I did a web-search and found pictures of a Ratcliffe Industries "TowLow" trailer. It looks dead-on like yours... and it also looks very much like a Hi-Lo, inside and out. Makes me wonder how much Hi-Lo "borrowed" from Ratcliffe in the early days to design and improve their trailers over the years. Maybe it was the other way around in that once Hi-Lo started upgrading models, Ratcliff followed.
One thing I really liked about the Ratcliffe design, in the photos it showed folding external corner struts that apparently locked into place to guard against the top falling, or drifting down. Such a design would
absolutely prevent the top from falling if a cable broke.
It looks like you may be on your own as far as garnering repair information from the HTF. Until your post, I'd never heard of this brand.
The photos I saw are copyright protected, so here is a link to the site:

Its unbelievable... how much the interior looks like that of our old 1967 Bon Voyage! The fold-down vanity in the back corner looks very similar, and HAH, except for the color, even the stove and reefer are the same brand!
Thanks for the update!
Jim
