I just came across a copy of the subject. It is a very complete listing of official tow ratings for cars and trucks/SUV's , motorhome chassis and dingy vehicles with chassis weight formulas, etc. that I have ever seen. The only way I know of to get it would be through a dealer sales and service department who subscribes to RV Business. They can get free copies by contacting Veradine Berkey at RV Business office in Elkart 574-295-7820 or
