Well, more of a second part to my last post which was made when I got to NY.
May not be repair end, but I recently took my 34+ year old square from northern AZ clear to NY, and then came back with my motorcycle, and a overloaded U-Haul behind it.
Saw a nice few squares along the way, and one near Bucket's home stomping grounds that had wicked head rests. ...Coming back across Oklahoma was fun, seeing the speed.. 65, ok, 70? Umm... 75? Not a chance with this trailer. 80?! ...Your smoking good stuff, this things as aerodynamic as a brick and im hauling an even less aerodynamic brick behind it, while geared for 55-60!
So in short, stress tested the heck out of that truck and my back. Back didnt fare well, that truck held up like a champ! Only part it ever hated, and most vehicles hate, is that absolutely wicked grade west of Albequerque NM. But dang was it one pleasant vehicle to do that run in.
