I recently added a pair of BAL LOCK-ARM STABILIZING BAR
to the rear scissor jacks of our 5th wheel.
They are mounted across the rear and made a major improvement in eliminating the 'tail wag' ...like when someone uses the entry steps or moves around inside near the rear of the unit.
Why BAL ?.... because I can use the scissor jack crank, same size as the bolt lock on the 'lock-arms'....during my level/stabilize routine....and I don't have to reach under by hand
like some other lock-arm systems.
hope this helps
