When you say "back and forth", I think of "side to side". If that is right,
attach small chains at each end (side) so that when the ramp is raised high
enough to allow lowering the main wheel, these chains become taught. Cheap
and easy!

All,

I have a new (to me) glider and trailer. Good rig, but like most things,
capable of improvement.

The ramp that extends from the back of the trailer for assembly has a
single, car style scissor (spare tire) jack for raising and lowering the
fuselage. It rocks back and forth a bit too much, and that makes it a bit
too unstable for my taste.
