Lifting tension on Rockwood A frame

I have a 2014 Rockwood A122S hardside. At each end it has something like a torsion bar that is under tension when the top is closed and aids in lifting the roof. Yours should be the same. Look at both ends, there should be a short curtain across the end where the roof and wall come together. Lift it up at the corners and you should see a white metal rod about 3/8” in diameter, one at each corner. That is the ‘torsion bar’. I doubt that there is a way to tighten the tension on it. But not sure.
