If anyone is using a 04-06 4x4 to tow a pop up camper. What size drop are you using on your draw bar/ball mount?

 

It really is kind of is determined by the wheel/tire size on the popup.
The tonque is usually a straight shot from popup frames.
A larger tire diameter might raise the whole shootin match up where a 2" drop would work.

Those itsy bitsy tires allow a 4" drop to be right for a even pull.
