I just wanted to update this post:

Last month I changed out all four shocks to Bilstein 5100 on my Tahoe. I left the stock springs. The rear end does not sag when the TM is hooked up. I will still use the WDH to transfer some load to the front wheels to maintain good handling.

The original shocks were in bad shape, and I should have changed them sooner.

With all due respect to your father, this was a myth in the early days. There is no way a WDH could do this, and it is not intended to do it. In fact, it would tend to drive the wheel more firmly onto the ground (or into a pothole) because the WDH puts some of the tongue weight back onto the trailer axle, distributing it evenly left-right.

This has also been my experience, and I've had several blowouts. The same has been reported by a number of other members of this board. I attribute it to the true tracking that the TM exhibits because of the far-back rear axle. The longer lever arm gives the tow vehicle more control over the trailer. Or to phrase it in reverse, when the trailer tries to sway, the long lever arm gives the trailer less ability to yank the tow vehicle around.
Quote:
I am probably going to get the WDH without antisway, but make sure I have something to which antisway could be added if I change my mind in the future. This is partly influencing my choice from the list I posted.
I think this is a great choice. It's the one I made, and I have never regretted it. In my nearly 20 years of long-distance TMing, I've encountered almost every conceivable sway situation, with no hint of sway.
Quote:
The Reese 66073 with the included antisway sounds like a very good WDH, but expensive if antisway is not really necessary. Personally, I'm leaning towards the Reese 66021 which could have standard antisway install afterwards.
My preference would be the 66021, which I bought for the exact reason you express. But of course the final decision is yours.

Shocks alone will not change the squat or sag when weight is added to the rear end. However, some B8-5100 series Bilsteins do have a built-in lift spring.

I don't know how the B5100 is engineered and designed for my Tahoe, but it did eliminate the sag with the TM hooked up.

As for your comment regarding my father's blow-out experience, it was probably the anti sway bars. But, whatever his set up, the trailer wheel remained off the ground. I was in error to attribute it to the WDH, but when I told the story I was still learning about WDH, antisway, etc.

My first trip with my 2720 was without a WD hitch and no sway control. All went fine. I checked the TM tongue weight and it was around 650 pounds. Then checked the F-150 hitch capacity stamped into the receiver - 500 pounds. Then checked the ball mount - 500 pounds. i then bought an Anderson WD hitch.

I did not get sway control for my TM. I agree that one should not experience any significant sway.

However, if the sway control that my father was using was actually able to keep the wheel in the air after a flat, perhaps that prevented other damage? It's probably better to make the "cage" that some have, and convert to round wheel wells for older TM.

Default Have gone with and without anti sway bar

Just bought a 2009 3124 after much searching - TMs are hard to find in Canada This one was in Ontario to drove out from BC to get it and then drove it back across the country. Read with interest the discussion about WDH and anti sway systems. After going over the TM the day before starting return trip decided the TM looked big (larger than our tent Trailer) so better to be safe and installed a new WDH and sway bar at the dealers. The dealer most strongly reminded us the anti sway bar had to be removed before backing up - a bit of a pain. We used the bar the first couple of days and then one night when we didn't unhitch the WDH for a quick get away next day forgot to put it back on and drove all day without it. Didn't notice any sway issues, didn't think it made any difference. So continued rest of the trip across Canada through mountains and prairies without it. This included lots of semi trucks and one day of strong crosswinds on the open prairies and was amazed at how well the TM towed with no sway. Not sure if we will bother with the sway bar from now on.
