I wonder about the trends in cars trucks and SUVs.
Trucks and SUVs keep getting taller and the suspension are more and more adjusted to give plush rides for the luxury vehicles they have become.
All of these things reduce the stability of the systems as evidenced by the increased rollover accident rates. This higher Center of Gravity along with unsophisticated rear suspensions means that with the roll center at the ground and the CG up high the roll coupling between the TV and trailer is impaired compared to passenger cars.
These raised trucks and SUVs on tall tires
(usually under-inflated) are accidents waiting on the proper conditions to happen.
I see this type of vehicle often on my daily commute inexplicably in the ditches on the side of the road. This is without trailers attached and NO combination handles better with a trailer than without.
As one of the contrarians on the forum I think that often the newer passenger cars with IRS and very much better suspension, often with Sports suspensions handle better both with and without a trailer as long as the weights are in line with good practice of less than 85% of the TV.
Since I have the small molded trailer for the lightweight and low drag for the reason that an excessively large TV is not necessary.
As far as not being able to tell the trailer is back there I don't know if I can't tell, what with the thing filling the center rearview mirror and having the extensions clamped on the side mirrors, that it is there from any poor handling of my VW.
My new VW that I am setting up for towing has the European trailer module to activate the trailer mode on the car electronics to adjust the T-ESP, engine fueling map, cooling programming, DSG shifting profile, etc. (the Ford Escape
does the same if the entire kit with electronics is added This changes the rating from about 2000 lbs to 3500 lbs.) The Westfalie OEM hitch fits where the VW engineers intended to transfer the loads to the unit body chassis.
The VW also is getting the Tekonsha P3 brake controller and Air Lift 1000 air springs to level the car with a load.
The old VW did really good without all of the bells and whistles so this one should be the cat's pajamas.
Personally I think that VW's reticence to rate their cars in the US is partially driven by the lack of support from their already pretty poor dealer network and the lack of the North American trailer electronic module packages. It has bee a real PITA to get the proper operation of the turn/brake lights
for US spec trailers. It would have been easier to rewire the Scamp for the 13 pin Euro specification!
My expectation is that this new VW Sportwagen will do a much better job of towing than the old one with 250,000 miles. 25 mpg is nice too.
I don't recommend anyone else follow my example because as an engineer I am willing to form my own informed opinion and deal with the issues. My Insurance company has no problems with it either.
