Look at these advantages:
Anderson fitting guide:
Okay, to help you properly we need a few measurements in inches:
A. With your trailer level, measure from the ground to the bottom of the trailer coupler – then subtract 1".
B. Now measure from the ground to the top of your receiver (top of 2" square).
The difference between the first and second measurements will tell you what size drop you will need (below). If the difference is 4"or less, then the 4" drop will work for your set up (in drop or rise position) If the difference is between 4" and 8", then the 8" drop will work for your set up (in drop or rise position) If the difference is greater than 8", then you may need a custom shank for your set up.
next we need to know if your trailer coupling/hitch is mounted above the van chassis or mounted in between the van chassis rails (like on a jayco outback).
The above listing is for 4" and for the coupling mounted above the chassis rails.

Andersen 4" Drop Weight Distribution Hitch
Great product and fantastic service
Very easy to hitch up and good stability, quiet
after having a spring type WDH for years the Andersen hitch is a game changer.
Takes a bit of setting up the first time, but well worth the effort. Does everything it says it should, quiet, no groans or clunks. We went from the tried and tested Hayman Reece V5 that had worn out. Completely different van to tow. Always thought the old one was fine, but I tell you what, there is something better. This is it!
