Hensly

I have a 29 as well and struggled with the many configurations (loaded, unloaded) and finally paid the big bucks for the Hensley hitch. As an engineer its the only thing that makes engineering mathematical sense, all others must use some form of friction to dampen what the Hensley fundamentally stops. All other suggestions boil down to dampen the sway (weight distribution, heavier truck, friction bars, etc), only two designs eliminate it. Only one is still in production with ProPride and Hensley. Without the friction loss my FE went up quite a bit as well. Not enough to pay for the hitch but noticeable.

Blue Ox doesn't use friction.

Neither does Reese dual-cam. It works without a friction device by both forestalling and resisting sway and only works when needed. It works similarly to a detent spring, which holds something from moving; it takes energy to over come the resistance of the ball and socket's action to compress the spring. The system also allows turning and backing without removing anything.

Wolf, Wolf, Wolf, we rely on your great ideas and technical knowledge for many things but in this area you seem to want to ignore the fundamental engineering facts. No mater what you do to the conventional ball hitch system, whether it be friction, springs (blue Ox) or cams (Reese) you are still trying to cover two major flaws of the system that can only eventually lead to trailer sway. First you are tied to a ball hitch that is a single point of force on your vehicle (pivot) and second that force acts upon you vehicle behind the bumper, way behind the center of gravity of the vehicle.

Fundamental! Why are fifth wheels so popular? They move the pivot point ahead of the axle, near the center of gravity. Why are conventional systems so reliant on did you balance the weight of the trailer , is your friction/spring/cam set properly, etc.... Because they can never overcome fully one design flaw,....they are designed to SWAY.

Hensley/proPride designs solve that flaw. They do not pivot on a ball and the center of gravity of the pull is moved forward by the four bar link, to over the axle. Four bar link, what a concept, don't pivot on a ball. The FBL has been used for centuries to translate movement to another point without pivot.

I do not own Hensley or work there and I had my first dollar ever earned (i.e. I'm Cheap) until I spent it on a Hensley. I never worry about sway any more, ever. I drive past semis, through howling rain storms, around tight corners and nothing bothers the Hensley. Do I wish it was cheaper, yes (its built like a tank). But I could sell it used right now and recoup much of my cost. If you don't want to constantly fret over is my truck big enough, is my weight distribution set right, its too windy, can I use my friction device in the rain, did I disconnect it when I backed up, etc.....put the big bucks down on a Hensley.

You can try and tell me your system doesn't have that problem, but it does by design. Is there a ball in the equation? It will eventually have a moment on some road that you need to change your shorts for. Mean while I'm relaxing.

Rocrider (R, R, R!), respectfully... you must have read something into what you think I wrote. Or simply had too much coffee today. I wrote nothing that would indicate I am ignoring any engineering facts. I also didn't misrepresent how the dual-cam functions. I actually do know the inherent flaw shared by hitch and ball towing systems... and like YOU, have no experience with a ProPride or Hensley. But, I reported facts based on experience with my hitch. When I consider my $00.00 investment in it, and the facts that the dual-cam works well enough for me, I have no future plan to pay $2500 for a hitch, even though I could sit for hours admiring the engineering masterpiece. It ain't new either, been around for many many years.

Thanks for the lesson on how the Hensley and Propride works, someone here might not have known all that.

I'm with you WW. VERY satisfied with my cheap, insuffecient, antiquated, ball hitched, poorly engineered, incorrectly mounted, etc, etc, etc, Blue Ox. It may not be the best, but it works VERY WELL for me.

Yea 2500 hurts. You can get em down to$1700. I am on the fourth coffee since my 4:30 am meeting with England. Love my Hensley. I will say I spent almost as much trying to solve my sway a $100 to $300 at a time. Between scales trying to get weight distribution right, three different hitch systems( I went too cheap early on), hotels halfway on my trip because the wind was too high, new door and handle bars because the sway was so bad that it shook my bike lose. Heck I probably spent three times what the Hensley cost. If you spent more than $30k for your rig, 5% on a hitch is a cheap insurance policy. I should get an insurance discount.

RocR. I read you message wrong; thought you said you don't own a Hensley. Like I said for my dual-cam there was a learning curve ("it was fussy") but the RV tech didn't get it right either... but I didn't go thru all the stages and problems you did... The setup wasn't that bad, but I knew it could be better so I figured it out. I chimed in because you said all non Hensley type hitches use friction and that just isn't so... forgive me for being me

I wish my $00.00 hitch had been a Hensley and I hope to own one someday.

No problem. I hate that the Hensley cost soooo much but it works so well , no fuss. My cheap nature still hates I spent so much. I'm glad when some find cheaper solutions.
