Reese Titan 34" hitch for towing car

I use a similar 2 1/2 hitch extension but generic. Mine is 18 inches from the hole to the end where you insert the ballmount. Do count your ballmount length in clearing the bumper. I cut mine down to shorter and drilled another hole from the 24 inch because otherwise, it extended past the bumper with no ballmount and was in the way when stepping to the step.

Shorter is better because it has less leverage on the hitch. My camper is called a 9 1/2 foot and 18 worked for me.
