Was curious about this statement:
IIRC max length is 110" wb for 20', then add/subtract a foot of length per 4" of w
Would this also apply to SUVs? Trucks tend to have high ride heights and mushy handling and steering. I'd think that an SUV with a tighter suspension and steering could handle sway better? All the modern SUVs (BMW X5, Mercedes ML/GL, Porsche/VW, and Jeep Grand Cherokee) have high trailer tow ratings (7k+ lbs) and have software to detect/reduce trailer sway (by leveraging the AWD, brakes and tranny automatically). I'd think for a midsize modern trailer (22-26ft) that this would be enough?
