I have been towing for many years with a variety of setups (except Hensley).
In 1990, I installed a Pull-Rite on a 1990 Chevy Van in an attempt to tame a 28' Prowler. I installed it myself with a $20 (Midas) tail pipe modification. The experience was nothing short of amazing, the Prowler became a baby carriage. I highly recommend the Pull-Rite.
I bought my 30' Award in 1995. As you may know, the Award was designed with tow ability the #1 priority. The Pull-Rite became a little "over kill", with the Award weighing almost a ton less than the Prowler. I made several trips with the Pull-Rite bolted in the center to simulate a conventional hitch without load leveling or sway control to test the Award's behavior.
When bought my new 1999 Chevy Van, I had the factory receiver installed, and purchased a Equal-i-zer. Chevy has changed the steering geometry in the new style van, which increases the influence a passing truck will exert on the truck's steering without the trailer attached. I did not expect the Equal-i-zer to cure that and it didn't. The Equal-i-zer tows like a conventional hitch with sway control, and that's about what I expected. Although it is not a Pull-Rite, I am fully satisfied with my purchase.
Each trailer/tow vehicle combination is unique, and many combinations can tow very safe using a conventional hitch. Others need a little help.
Happy camping,
