My name is Tim, I am an RV tower. (Respond, Hi! Tim) I have an RV that is in the 7000# capacity range and I used a distribution hitch with a sway bar. My wife complained of the ride and lasting discomfort. Happy wife happy life and conversely not to mention you have to sleep sometime. This being within the capacity of an Andersen hitch I made the purchase, installation and hoped for the best. Result, better ride, easier hook-up and happier wife. 2 cost maybe but refer to above. Forgot to mention, often w/o looking in mirrors I nearly forget we have a trailer attached, except when noticing fuel consumption.
