Drilling a hole

When I open the tailgate of our new 2016 F-150, the gate won't go completely down. It is stopped by the electric tongue jack. I turned the jack 45 degrees, and most of the times the tail gate still won't go down. Approx 1/4 inch missing.

My RV tech tells me he can drill a new pin hole for the pin that holds the ball mount in the hitch receiver tube so that the ball mount will be may 3/4" further out of the receiver. This would allow the tail gate to fully open. He tells me that this will not alter the integrity of the ball mount.

Any opinions? (I hope my description is clear enough)

  • There are shanks with more than one pin hole. That doesn't mean you can drill a hole in any shank and have it keep the same strength and weight rating. Whether it affects the integrity of the shank depends on the quality of the steel used in the shank as well as how much heat is generated by the drill bit. Lots of heat will compromise the integrity of the steel. If it can be drilled it's best done on a drill press at a slow speed with some kind of coolant.
  • Hmmm,opposite opinions! I wish I could post the picture of my actual ball mount and shank. But my work computer is not set up to let me use the public photo web sites.

    I will further investigate. Maybe even call Reese, as suggested.

    thanks for your input guys.

  • If you have a solid steel shank and it will still be fully engaged in the receiver, I would do it. I wouldn't trust a dealer to do the drilling unless he has a milling machine. Take it to a machine shop.
  • What are the current specs on your shank? 1000# tongue weight?

    My concern with drilling a hole would be if the shank was designed for an added hole? As you can see, the Reese is derated by 33% to use the second hole. All things being equal, If your shank is rated at 1000#, after that second hole is drilled, you could be limited to less than 700# of tongue weight. Can you live with that?
  • I would not think twice about it. 3/4 of an inch is not going to make that much difference. I would do it in a heartbeat. I have been a welder and fabricator all of my life. Just my opinion.
  • It WILL lower the the weight rating of the ball mount.

    Reese has a shank with 2 holes
    Back hole ---------1000# rating
    Front hole --------1500# rating
