I have purchased the dual cam system from Reese, but have not installed it yet.
May question is about mounting the frame plates on tubular frames. As I understand it, after drilling a couple of 7/16" holes in the appropriate positions, these flanged head, self tapping screws are screwed in & torqed down to 50 #.
Now a set screw & "jam" nut tightens it up on the other side.
Maybe I have just towed with the old "candy cane" type spring bars/trunnion hitch too long......because I have all kinds of nightmares @ one or both of these screws working loose. It just doesn't seem like very much to handle the strain on them.
Has anyone else ever had this concern ???
