Default Re:Tricks for Mechanical Advantage

I have occasionally found that when either shell is almost fully up, and I need to tweak the position a bit, it is easier to grab one of the (now almost vertical) lift arms (the white rectangular arm, two per side per shell), and lean in the direction I want it to go.

T_C mentioned levelling, and he is right - trying to open a shell even slightly uphill is VERY difficult. Someone on this board (I apologize for not knowing who) put this fact to his advantage. IIRC, he unhitched, then dropped the tongue jack slightly below level, which made it easy to open the front shell. Then he raised the tongue jack slightly above level, and opened the rear shell. Finally, returned the tongue jack to level and lowered the stabilizers. Obviously an electric jack makes this process quite a bit easier.
