I was just given a 77 Palomino - hard side. When the guy showed me how to set it up, he climbed inside, lifted it on his shoulders and pushed out the hinged walls to get the top to stay up! There are bars/poles/braces on the outside that have collars that lock over the hinge once it's up, but no evidence of a lift system of any kind. I even crawled underneath to see if there was any evidence of a cable/chain system ever being on the trailer and can't find a trace of it. 1) Is this normal for this era of pop-ups? 2) Any suggestions on how to "make" a system for it?
