In a group of "old timers" talking of their experiences, there was agreement
that NO offbrand hitch balls should be used such as those sold at KMart
or Walmart of flea markets, etc., just because they
are less expensive. It was agreed that the only acceptable one was
by Reese but even then they should be replaced depending on the miles covered
and the kinds of stress (rough roads, etc.) and
that the ball must be 2 5/16" and l0,000 pound rating.
Offered for what it is worth.
