• Locking Hitch Pin Kit Recommendation for 15K Curt Adjustable 2-Ball Mount
  I recommend using the Curt Lock Set # C23556 for your Curt Adjustable 2-Ball Mount # C99NR. This comes with a lock for the hitch receiver and one for the ball mount platform. Even though your platform uses 2 pins, only 1 locking pin is needed to secure everything to your vehicle.

• Anti-Rattle Recommendation for 15K Curt Adjustable 2-Ball Mount
  To add an anti-rattle device to the Curt Adjustable 2-Ball Mount # C99NR I highly recommend the Roadmaster Quiet Hitch # RM-061 simply because it's a tried-and-true solution that's easy to use and still very effective. The Quiet Hitch essentially clamps the shank of your ball mount to the inside of the hitch receiver and keeps it from moving that way. I've attached a review video of this system for you to check out.

• Will Curt Adjustable 2-Ball Mount Work With 2024 Toyota 4Runner SR5 Towing Small RV
  Hi David; more than likely the answer is yes. The Curt # C99NR will be able to handle a small RV and has a 4-1/2" max rise and 5-1/2" max drop.

• What Is The Towing Capacity Of 2011 Ford F350 6.7L XLT SRW Crew Cab 8' Bed?
  Hello CJ, thanks for reaching out. Based on the towing capacity chart I found online, the bumper pull capacity of a 2011 Ford F350 6.7L SRW Crew Cab is 14,000 lbs. The Curt Adjustable 2-Ball Mount # C99NR has a 10K capacity when used with the 2" ball, and a 15K capacity with the 2-5/16" ball.
