Tow ratings by the manufacturers have always been a crapshoot. They size up the vehicle, they size up the engine, they size up the competition, and the marketing department comes up with the number. That's going to change in the future, starting in 2013 model the SAE J2807 standard
puts an end to the arbitrary nature of tow ratings.
Anyway, those numbers can't really be cross shopped right now, and that's what the new standard will fix. To give an extreme example, going back to 1989 my old Cherokee (in auto form at least) is rated to pull 5000lb, but there's no way that my 4.0L would keep up with the Pentastar each dragging 5K up I-70 to Eisenhower tunnel.
