Those are only 24". It doesn't seem like CW sells the 30" any more. They are on the site with no price listed. Kind of weird. eTrailer and Amazon do have them. I am thinking I will need the taller type if I install the trailer lift kit. What part of the country are you located in and is the $90 including shipping or extra?
I'm in Appleton, WI Thirty miles south of the Green Bay Packers.
