Will-
I have an Andersen WDH for my 3326 King, which has a front slide. You'll need to fashion some spacers to push the outer brackets away from the frame, otherwise the threaded rod & bushing runs into the lower part of the frame that supports the slide. I stole this idea from Edugo here on the site. I took a couple pieces of 5/8" stock and drilled holes to match the outer bracket, including the tapped hole for the set screws. Then I had to drill out the threaded hole on the original bracket. Doubled up the spacer and the outer bracket, used longer bolts, and good to go. The Andersen works great. I can take pics of the setup if you like.

Quick note: It isn't truly greaseless. After about 500 miles I started to get a creaking noise when the hitch was under tension. Although the ball moves side to side with the trailer, that does not account for any up & down rotation of the coupler on the ball. Andersen told me a little grease on the ball would do the trick.
