I read and agree with the article. Most points are very clear and the only questio I have might be related to the EU and rest of the world ratings vs US.
The US manufacturers are just now considering meeting the SAE standart for rating tow vehicles. Currently the manufacturers rate their (mostly trucks) based on their sales goals and some internal engineering criterion.
SAE J2807 is the proposed standard and manufacturers considered making the switch to a standardized system, but with the competitive pressures they all put off publishing their ratings under the standard.
When this new standard is actually used the ratings on many cars and trucks will be rewritten with many cars increasing their ratings and truck being derated.
This new standard includes towing up one of the most difficult hill section in the country while maintaining engine and transmission temps within limits.
At least the EU has testing procedures for their cars and the relatively few light
In my opinion the EU rating of tow vehicles is probably pretty good. The tongue weights could be higher since the total weight
is really limited by that factor more than total drawbar pull ratings.
For example the VW TDI is rated starting on a 12% grade. No doubt it is capable and My 2009 JSW TDI can tow the weight
very comfortably with the OEM Westfalia hitch the 175 lb tongue limitation is more constricting.
I am very interested in the Cam-AM equilizing hitch for the VW.
I am thinking of upgrading to a 2015 or later Golf stattion wagon to tow our Scamp
16' and the tongue limitations are the largest concern and the reason I did not go to a Casita
17' or an Airstream instead.
I am currently in a rebuild on the Scamp
and working on lengthening the tongue and balancing the mass to keep within the car limits.
