[A/S] Re: Sad News
Tony, I'm sure sorry to hear about your loss, but grateful ya'll are
okay! Let me give you some advice for a new rig. First, get a tow
vehicle with a long wheelbase and short overhang behind the rear
axle.
There are only two hitches that eliminate the effect of sway on the
tow vehicle, and that's the Pullrite and the Hensley. They move the
pivot point to the tow vehicle rear axle where the trailer has no
leverage on the tow vehicle. The Pullrite essentially turns the
trailer into a fifth wheel, with all the advantages and disadvantages
thereof. The Hensley essentially turns the rig into a motorhome when
it's straight. These are the only two hitches where the tow
vehicle's ability to turn the rig IS NOT AFFECTED by the hitch's
resistance to sway, so the latter doesn't have to be compromised to
provide the former. You can pivot a Hensley or Pullrite with your
fingers.
All other sway controls fight and try to reduce sway. They don't
eliminate it.
All other sway controls fight the tow vehicle turning the trailer as
much as they fight the trailer turning the tow vehicle. They are a
compromise. If they are set tight enough to be effective against
severe sway, the tow vehicle can't turn the rig. If they're loosened
up so they don't bind in a turn, they have much less ability to to
dampen sway.
The Equal-I-Zer is simply a friction sway control on each side of the
tongue. While it innovatively uses the spring bars as part of a
friction sway control on each side, it's no better than any other
friction sway control at damping sway. It CAN'T be regardless of
what their marketing says.
The Dual-Cam also fights and reduces sway with the cam action that
tries to return the trailer to center. But it also is limited in how
much it can fight sway. If it fought sway significantly, the tow
vehicle couldn't turn the rig.
There's an Airstream dealer in London, Ontario who sets up rigs
pulled by woefully inadequate tow vehicles, such as front wheel drive
cars and minivans. And they're dragging as much as my 9800 lb 34'!
I don't condone this at all! But part of their testing is doing skid
pad runs with various tow vehicle and trailer combos, dragging a
trailer through the cones, and in every case, a Hensley increases
speed through the cones by 10-12% over a conventional hitch. From
what I hear, Hensley shows the Intrepid going through the cones on
their video, and if that's the case, I consider it irresponsible
marketing. A Hensley should be used IN ADDITION to having a proper
tow vehicle, but from what I hear, they market it as a cure for
mismatched rigs. But their marketing doesn't override the fact that
it's the best hitch design on the market.
Having a Hensley or Pullrite is like wearing a seatbelt or a
motorcycle helmet. The odds of needing their capability is low. Many
go through their entire life never needing any of them. But when you
do, they're priceless. The only folks who'll tell you that you don't
need a Hensley or Pullrite, or that those hitches won't help, are
those who don't use one.
