We have a 2014 Tacoma as well, Double Cab/Long Bed. When the tanks are nearly empty and little cargo in the truck bed, the towing is fine. With more in the tanks and some cargo in the bed, it starts to be an issue. The tongue is lengthened to accommodate a generator basket (we keep it empty while towing).
I am considering a weight distribution hitch, sway has not been an issue.
I wonder what could be different in our setup and Flyrod's to make a difference?
We have had many admiring comments on the Oliver. We have given several tours including a very nice couple in Austin who have a Casita.
