52MPH, 55MPH, 58MPH, 62MPH.......
what it comes down to is that a good number of rigs on the roads are marginal or less so there is a strong possibility that problems loom.
When the rig is right it will track and perform safely.
There was an article 60 years ago in Popular Mechanics about this 50's Mercury that towed a trailer over 90MPH and it remained stable.
Note we tow at around 60MPH, sometimes less if the road conditions warrant. Never had an issue of sway, not even a whimper from a passing 18 wheeler.
PS.... The vehicles today are far more capable in every way than that old Merc. Combination set up is key for a successful ride.
