I found some more information if anybody needs to replace a torsion bar in your awning
NOTE: If the awning is installed on a coach, complete the following steps on a step ladder, with the awning fabric unrolled two feet from the awning rail. The unwinding can also be done while standing on the ground and the awning fully extended and the opposite side rafter locked in place. The torsion spring will be wound with 8/eight more turns in this position and is extremely dangerous.
The words "extremely dangerous"
means I'll be using a step ladder
