Tom,
I tow with a Grand Cherokee and did experience trailer sway at about 55-60mph.  It's maddening and frightening.  I found that if I inflated the trailer tires to the correct air pressure (60psi) the trailer sway went away and I can now tow at 65mph.   - Rob

I agree this has been valuable. Thank you everyone.

 I wonder about the track geometry.  My trailer has a wider track than the
grand cherokee.  After about 55 I get some wagging.   But from the 10%
tongue weight math I am still missing 150#. Probably exposing my great depth of knowledge... I will look at quick release tiller so the rudder+ can travel ahead of the axle at least... I'm not too exited , although it's cool and functional, of the idea of remounting the outboard as the connections stand.

Aside, Does anyone have resources or tips on welding repairs for the galvanized trailer? I understand to grind away all zinc and use a cold galvanized paint.
