One other thing I have learned about a 4-way pivot Reese Hitch. Do not use a long shank lock on the release handle. Under the right circumstances the hitch can pivot and the lock can push the release handle up. We came up a hill and made a hard left. This pivoted the hitch hard to the driver’s side. The base of the lock hit the leg and pushed the release latch up. Trailer stayed hitched, but no more long shank locks.
We have had this 16K Select since 04 and the mentioned issue above has been the only one. When we buy a new truck we will most likely replace this hitch, the new DRW trucks all have tow ratings above 16K.
