This is something we have never done before: publish a follow-up story. We heard so many personal experiences about towing and haul ratings that a second story seemed like a good idea.
When we were building the Shelby facility in Gardena my son Michael and I transited the Sepulveda Pass more than 900 times.

We would get up in Redondo Beach every morning at 6:45, blast up the 405 for 25 miles, over the 1,100 foot Sepulveda Pass, to get to the methadone clinic in Van Nuys by 7:30. Ten minutes later we’d be doing the reverse to make it to Shelby’s in Gardena by 8:30. In the 1 1/2 years we were there we summited that pass more than 900 times. We got to know it and its inhabitants pretty well. We even had pet names for features of the road. Over Steer Bend and Pay Attention Corner were two of our favorites.
B.T.W., if you are traveling and on methadone, you have to get a temporary card from your home clinic to a clinic near you. Early in the morning is the best time to go, for obvious reasons!
When we passed a haphazardly driven vehicle towing a haphazardly loaded trailer up the Pass, we shook our heads as it barreled past us on the downside. We never saw an actual crash, but we saw a lot of Death Wobbles, steering corrections followed by over-corrections, etc. There was lots of evidence of crashes too. The calligraphy made by the locked brakes of the towing partners as they pirouetted across several lanes of traffic was really quite interesting, until they kissed the side of the Pass. A never-ending supply of clothing, bits of cars, trailers, and household goods lined the hill, always on the downhill side where the dancers came to a stop.
In the first story, we referenced Society of Automotive Engineers ( S.A.E.) standard J2807, which addresses vehicle gross weight and towing requirements. The Society has an interesting web site, www.sae.org/volunteer, that may be of interest. .
Popular Mechanics (remember reading them in study hall?) has a good site.
It’s four long pages long and mentions things such as “equalizer bars” and “anti-sway hitches.” My feeling is, if you don’t know this stuff by now, you’ve never been interested in it and are not likely to absorb it with one or two readings. And remember a little knowledge can be dangerous. There are companies out there that offer classes for newbies.
Consumer Reports has a How to Tow site. The text is full of “might be” and “some-times,” which I guess is necessary, but not very comforting.
Even AARP, American Assoc. of Retired Persons, has a guide for old folks hitting the road for the first time in their new motorhome or camp trailer (yikes!).
In my home state of Utah, Grandpa and the kids can head out in their new 45 foot motorhome weighing 26,000 pounds, towing a 20 foot trailer. 65 feet from the front axle of the tow vehicle to the rear axle of the trailer is the maximum allowable length. In practice, that results in a train over 80 feet long and weighing over 40,000 pounds — with just a regular driver license.

As seen in our first story, even the manufactures can’t–or won’t–say what your new rig is capable of doing safely.
My friend Bob is one of the few owners of a camp trailer that actually uses it. He travels and camps several months of the year. We were at his RV storage facility when he mentioned to the proprietor that his new Yukon doesn’t tow as well as the previous one. The proprietor said he may want to visit a local alignment shop that has a reputation for improving tow vehicles.
The shop took us right in, and the owner explained that most new cars can only be adjusted for toe. In the “old days” you could adjust for caster, camber and toe. Some could even be adjusted for bump steer.
The front end of Bob’s new Yukon was made by a vendor using parts, sub-assemblies and assemblies from all over the world (read low cost) and was designed to drop into the assembly line with no adjustment required. Apparently, if you know what you’re doing, you can improve on the “good enough” factory settings.
For about an hour and 1/2 we watched the owner loosen, tighten, shim, bend and persuade, even giving it a couple of loud whacks with a big hammer. Using his four-laser-beam alignment rack, he made both front wheels point in the same direction, with just a bit of toe-in, and increased the camber to aid tracking and improve steering feel. Bob’s new Yukon “towed like a dream.” especially in downhill corners.
With all the lack of information, half-truths and self-serving lies out there, we decided the best thing to do is, ”Ask the man (or lady) who owns one.”

Find an RV storage or repair shop, or visit an RV camp ground, find a rig like the one you own or anticipate owning, and ask the owner what their experience has been, and what they would recommend. This tag line from a 1930 PACKARD ad may still apply.
