Well standing on the shoulders of giants... @JimVandegriff , @ohmman and others... I've decided to pull the trigger on a 2018 Airstream Bambi Sport 22. I've really enjoyed reading all the Model X/Airstream posts to date, and I so thoroughly enjoy road trips with my Model X that I want to take it to the next level. I intend to pull the Airstream with my Model X 90D with the tow package installed recently by my local SC. I'm evaluating different trailer hitch setups at the moment as I have about 6 weeks to get ready before the new Airstream arrives. The three hitch systems I'm looking at are all of the anti-sway variety: 1. Equal-i-zer The Equal-i-zer seems to be the tow system of choice thus far among Model X towing pioneers. My only issue is I don't like the way the system relies on pure friction of steel on steel to accomplish the anti-sway function. Another issue is it uses a set of many washers (think stack of coins) to accomplish preangle adjustment on the hitch ball and alter weight distribution. This system seems a little "Rube Goldberg" to me, but I'm not an engineer. The fact that others are using this system on the road without apparent issues means a lot however. 2. ProPride Hitch This really is a whole different animal in terms of hitch systems. It may be overkill for a sub 5000 lb trailer but I like the technology employed. The ProPride main unit consists of two 3/4" thick links that project the pivot point of the trailer forward to near the rear axle of the tow vehicle. By not allowing the trailer to pivot side-to-side on the ball, trailer sway is eliminated. The downside here is the increased tongue weight because of the weight of the apparatus itself and the high cost--nearly three times the cost of the Equal-i-zer. Again, this system is really designed for all trailers including very heavy trailers and may represent extreme overkill. 3. Hensley Cub Of all the hitch systems I've looked at, this one is my favorite from a technology perspective. The Cub model is specifically designed for smaller trailers (between 2,000 and 6,000 pounds (12 to 24 feet)) and a wide variety of tow vehicles ranging from cars and compact SUVs to pickup trucks. It is the only trailer hitch on the market that doesn't use friction to control sway. It uses a proprietary converging linkage system that effectively allows movement on the ball in every direction except side-to-side. From the company's literature ..."Side-to-side movement is forced to go through the linkage system which is one directional. From the trailer side, the linkage is solid. Pivoting by the linkage must be initiated through the tow vehicle. The system’s design is inherently stable. Best of all, it functions mechanically, without the use of friction so it exhibits consistent and predictable behavior regardless of changes in weather or road conditions." This hitch is supposed to allow the tightest turning radius of any hitch system on the market because of articulation of the linkage around the ball. Interestingly it is supposed to bring the tow vehicle slightly closer to the trailer which reduces wind resistance and may be especially well suited for use with a Model X to improve range a tad. It is about 2 1/2 times the cost of the Equal-i-zer. A good video showing how it works is here... Hensley system video Sooo...help me decide! Any input from experience towers would be appreciated. Obviously safety in towing is my number one concern so I want to make a good decision here.
