Re: Tow a 4100lb boat with the 3.7L AWD WK
I think this may be a bit of a stretch, though hopefully someone that has towed with the 3.7 can chine in.
Personally, I wouldn't risk it (I assume the engineers have listed 3,500 lbs. for a reason), but I am sure others who have towed with the 3.7 can add more to the conversation than me!
If I were to do it, I would make sure I had a load-levelling hitch and trailer brakes at a bare minimum.
Another thing to keep in mind: You may void your insurance on both the boat and Jeep if you are towing outside of your weight class and were to get into an accident - even if it is not your fault.
