When I was trying to find a tow vehicle (which also needed to be my wife's daily driver, so F150, etc., was not an option), I found that the tow ratings in the US were consistently lower than the European ratings.
I ended up with a Volvo XC60 with, as I remember, a 3500 lb tow limit. Believe in Europe it's 5000.
Reading similar discussions on various forums, the litigious nature of the US (sue over everything/anything) was often viewed as one of the primary reasons.
FWIW, I've had no problems towing with the Volvo.
