One of our original forum organizers, Denny_A, posted a tutorial on adjusting the torsion bars. I think this is it.

In addition, there is a sometimes-helpful trick, based on Digger's comment. When it is time to open the front shell, lower the tongue of the trailer a couple inches below level. The shell will open more easily because it is moving "downhill". Variants of the same trick, of course, work for opening/closing both the front and rear shells.
