You actually don't keep the ball "compressed into the front, and the way the yoke holds the head square with the tongue, it doesn't matter, again, unless the yoke slips.

The yoke is held square under the A frame with a bar setup that is clamped to the A frame with "U" bolts, and in extreme circumstances like lagging trailer brakes, it will slip. Think of the yoke as a tongue on an old four wheel wagon.

I'll have to have Cheryl back it sometime and get out to watch the difficulty I've never noticed.

There was an interesting thread over on rv net a few months ago. A fella there was having sway problems with a large white box toy hauler behind a Ram 2500. He went through a LOT of work using a conventional sway control/WD hitch, multiple passes at the CAT scale, etc, trying to eliminate a sway problem at highway speeds. Nothing worked.

He bought one of these pivot projection hitches, and it "eliminated" his sway issues instantly.
One of my take aways from this whole discussion of this design vs conventional design hitches is that if you have a problem child trailer ( and perhaps a marginal tow vehicle, from a stability standpoint ) then one of these hitches may provide the solution you are looking for.
The flip side of this is that if you have a trailer that is fundamentally stable in it's setup, then the added expense and weight may not be worth it. When I installed my "conventional WD/sway control" hitch ( BlueOx ) on my SOB trailer, I took it for a test drive, and tried to make it sway. Yanking the steering wheel back and forth at speed, also, dropped the right side wheels off the edge of the pavement, and pulled back up onto the road. No sway. All I managed to do was re-arrange some loose stuff inside the trailer, and "open some cabinet drawers".
For me personally, I would not hesitate to buy a propride if I felt I needed it from a safety standpoint. But at least for this trailer, and this truck, what I have is working correctly.
Not all trailers tow the same, and not all trucks handle the towing the same. Use what works for your particular lash-up.

And yes, I know what "good towing" feels like. I have four trailers I tow on a regular basis ( two bumper pulls and two different goosenecks ).

Another way to view it is like the old yoke's on early model Fords that held the axles in place.

Or, take the Hensley struts loose from the A frame, and tie them to a common point under the A frame.

Steve,

Could this be the set up you saw at JC? After playing with my vice grips, this appears to be the only way to immobilize the head.

That looks about right, Ron - does it "freeze" the head from moving? I think Jackson Center used bigger vice grip clamps and the handles weren't pointed out (left and right) but both with handles facing forward of the hitch.

If that locks it, I think you got it!

I just installed a Hensley last week for the first time. It took longer to read the manual than to actually install it. Much less than an hour and easy to do.

Steve,

Thanks for your reply. I'll try and see if I can lock up the head with the vice grips going the other way. Looks like a trip to Harbor Freight will be on my schedule for next week to pick up some larger vice grips. Now where did I put that %20 discount paper?

I have not noticed this backing "thing" at all. For that reason,
I'm not going to spend the time analyzing it.

I have had a lot of opportunity to watch the hitch while backing, because my wife always backs the trailer while I provide guidance and obstacle avoidance. I am 100% convinced, if this phenomenon exists on the ProPride, its effect can be measure in a few inches at most.

Yeah... For everyday use this is a nonissue. If you are working with very close tolerances.... That may be critical. Then Again I have a 34'

Don't use the vice grips UNLESS you are using the ball head extension like the factory uses on their tugs. If you clamp it down that way with the the stinger hooked to your truck like normal towing likely you will need your check book handy. Just sayin' ....

I don't know where the pic went in Brian's #44 post in this thread - but it showed a tractor with a particular contraption on it for ProPrides - which is different than the one they use for Hensleys- and they have one for PPs with a 2.5" hitch (Sean overnighted it to them when we were in for service and they needed it...).

I don't know exactly how they set it up but your point is well taken. If any questions, call Sean for sure!

Idon't know what happened to that picture, either. I will repost all of the applicable photos.
