Been looking for an example of ratings...going up to and over...and fatigue failure...
Just a maybe some will understand that Laws of Physics"...
That 2" dia ball has a rating. As does the 2 5/16" dia ball. As does all tow balls
The one that comes with that U-Haul Rental has had hundreds to thousands of different drivers and tens of thousands of miles
Some just drive it...too many abuse it because it is not theirs (IMHO, lease vehicles are in the same boat)
Will break on the OP's trip ?....most likely not, but there is a chance Mr Murphy might cross his path during that trip...
Same thing with the forever disbelief here on these forums of the OEM's ratings for TV's...heck anything out there...
