Agreed. Don't want the tail wagging the dog!

You will be pulling a 4000 lb trailer with an 7000 lb vehicle. To me the notion of a WD system on that setup is rediculous
After my trailer had yanked me off of the road, totalling the tow vehicle and reducing the trailer to a pile of twisted junk, I visited a regional auction junkyard where totalled vehicles are held and then auctioned every six weeks. There was an area of at least an acre and possibly more with nothing but those trailers you describe in your post. Very nearly all of them quite clearly had been trashed by out-of-control sway events. I had not used a sway control hitch, and I saw no evidence of sway control hitches on any of those trailers.

Lost of sway control events, called "snaking" in Swedish studies do occur relatively rarely, but the same can be said of 18-wheelers jack-knifing and engine failures on helicopters. I did a heck of a lot of research, including asking some very senior state troopers about loss of sway control accidents with trailers. It is extremely hard to prove a negative, but I was able to find numerous accident reports on loss of control events while pulling trailers on ball hitches aft of the bumper. What I could not find was control-loss reports on either 5th wheel hitches or, and this is the critical point for me, on trailers using the Equalizer, Hensley, or Propride hitches.

The Swedish studies I read on the subject concluded that any trailer attached to a ball hitch aft of the bumper has the potential to generate an out-of-control sway event. It is simply a matter of having the right combination of circumstances. As I wrote earlier, I towed several different trailers many thousands of miles before that one-time event. I, at least do not consider myself a person who worries a lot, and my intelligence level is sufficient to have a master of science degree. I also don't have "more dough than common sense."

There are those too who insist that remote sensing tire pressure gauges are a waste of money. Last month that sensing system saved me two expensive tires and probably some significant damage to my trailer wheel wells. Another analogy is the fire extinguisher in the kitchen. You may indeed go for many years, and even a lifetime without using it, but that does not mean that fires don't start from unattended food cooking on a stove.

The OP asked if he needed a WD hitch to tow a 4000 lb Argosy wirh a 1 ton pickup. I replied to that query.
Nowhere did he, or I, mention sway control.
If you wish to explore the difference between sway control and weight distribution these forums are a good place to ask.

@Ultradog. Please pardon me if my response offended you. My understanding is that you posed a new question that appeared to refer to me and the others on this forum:

<QUOTE>"Are all those people are just dumb and uninformed?
Are Airstreams particularly difficult to tow?
Is this community made up of people who tend to worry a lot and have more dough than common sense?"<ENDQUOTE>

My response was to your questions and to those who recommend towing without any supplemental hitch.

Ok, my opinion through experience. If you have a three quarter or one ton truck,get a ball amount at approx the correct drop and hook up your trailer. If the front end rises less than a couple inches you do not need sway control. Go to etrailer and buy a heavy duty ball mount and two sway control tabs. Have the tabs welded to the mount, cost me thirty dollars. Buy the two small balls needed and two sway control units, available most places that deal with rvs. If you do not have the ball mount on the frame, you will have to install one, either bolt on or welded. Most are bolt on since it us only for sway and no weight load. Many older trailers already have this mount since it was in common use. To answer your question, no you probably don't need WD, check it out as I have posted, but I highly recommend sway contol.
