I'm glad I stumbled on this thread. I am having problems too with my lift system.
I have an older (86-89)sun lite eagle with the torsion system. I had to make a roof repaire where the mounting bracket twisted itself from the rotten wood it was attached to. Having made the repair and dismantling the lift system and re attaching it, my roof is now pulling too far to the side I repaired. It pulls the canvas too tight and the roof hangs too far to one side.
I have the bent U shaped tube and the other tube that attaches to the torsion bar tube unbolted from one another and unbolted the front of the torsion tube and i can pull it towards the camper cab over area to pull the tube off of the rear bracket and expose the spring bar. Where I am confused as what orientation do I start the down tube(that connects to the torsion tube) I can only get the torsion tube over the spring bar in 2 positions. One is where the down tub is aligned with the roof and the other is pointing down Towards the floor at maybe 45 degrees from the roof. Do I crank downwards from the roof to tension and reconnect the tubes? That seems like that would be way too Much tension. I hope I made things as clear as possible. It's hard to describe. Has anyone made a video of how to tension the system? That would be great if there is one out there.

I have just gone through the process of installing a new Heco gear housing kit and new crank sourced from canvasreplacements.com. Way tighter. Was previously sloppy leading to worn teeth on crank and idler gear. Have since been told to stay away from grease and use a dry lubricant as grease traps grit and contributes to wear.

I have a 2004 Hallmark with torsion bars and have been told that by disassembly and reversal of torsion bars you can can get a number of years of service. I have not been able to source new torsion bars.

Ok picked up a 2012 Northstar tc650.  Seller opened and closed few times.  I just tried to open my self.  I don’t think I had the crank inserted all the way and realized one corner was stuck.  Walked out and freed the corner and started to crank. Seemed hard. Lifted few inches and crank gears sheared of. And roof is a few inches up.   It’s in the backyard 


i had tent trailers for years.
