Longer Weight Distribution Shank Recommendation for WD System Used on RV

Question:

The hitch on my RV is tucked in underneath. Roughly 10.5 inches from bumper cover to center of hitch pin. Im trying to decide what length shank I need for weight distribution hitch. A 12 inch shank ends up flush with the bumper. Then ad 4.5 inches for the Reese ball mount. This seems close to me. Should I by a longer shank? Is it possible to buy a complete hitch with a longer shank? How close can the ball be for turning? The trailer Im pulling is an 18foot tandem Axel v nose enclosed. Not loaded very heavy. Maybe 1500 pounds

The Curt weight distribution shank part # C17122 measures 16 inches in length. This would be your ideal solution it sounds like.

We do offer WD systems without shank so that you can supply your own to match your needs.

The best way to pick out a weight distribution system is to base it off of the loaded tongue weight of the setup when it is loaded and ready to tow. This figure also includes the weight of any cargo behind the rear axle of the tow vehicle. I attached a help article on determining tongue weight for you to check out as well. You will want the loaded tongue weight of your setup to fall right in the middle of the tongue weight range of the system you use.

Once you know your tongue weight you will want to check out the link I attached that has all of the weight distribution systems we carry. You will be able to select your tongue weight from the filters to see what would be rated for your setup. Everything at this link does not have an included shank so you can use it with the Curt shank.

For a 2 inch ball you would want part # A-90 and for a 2-5/16 inch ball # 19286.

You really can't make too tight of turns with a WD system since it will put a lot of strain on the system's bars. But turning clearance in general will vary largely on the trailer and tow vehicle.
