Op...please consider the EXPERIENCE of those who have had the pleasure of towing a large trailer with a good handling vehicle.
fwd doesn't make for a bad tow vehicle in and of itself. The Traverse is a great tow vehicle with a great handling suspension.
My Pentastar doesn't even blink at 3500 lbs. High RPM's...not even close...my V10 had to run more RPM's to maintain speed at GTW than my Pentastar.
Keep it in the ratings, dial in the Weight distribution hitch and sway control, use a good brake controller and enjoy a comfortable tow.
You do not need a truck to tow that little trailer.
Thanks!
