Just an FYI for anyone using an older model Andersen WD hitch. There is an upgrade kit available that includes the newer model plate and the WD anti-sway assembly. See https://andersenhitches.com/collections/weight-distribution-hitch-parts-accessories for parts. The upgrade kit is not noted on their website but I stopped in last week on my way back from a camping trip and learned it was available for $100. They also offer a 20% military/veteran discount. Not sure if a local dealer has the same offer or what shipping charges would be.
Interesting. I'll look into that. I guess I'll have to email Andersen about it since it's not on the web site c
