This one appears to have begun with a little help from a passing SUV. He wasn't speeding, doesn't appear to be windy, road looks normal, no evasive maneuver, just oscillation that continued to get worse. I'd bet lunch the owner lightened tongue weight to accommodate the Expedition. Doesn't make him evil, stupid or careless. He may have been ignorant of how little it takes off the tongue to induce sway.

My Layton is pretty light on the tongue. How much? Don't know, never weighed it. If the ol lady puts two suit cases of cloths on the bed (rear bed) my trailer will sway even with my sway bar adjusted as tight as I can get it. If I move those to suit cases up front to the dining room; no sway. Just like magic!
I bet the suit cases weight about 50 to 75lbs apiece and it's not on the rear bumper. In fact it's about 4 to 5 foot inboard.
Just goes to show how little it takes with a trailer with a light tongue weight.
