Nice payload for a 1/2 ton. When I went looking for a 1/2 ton I couldn't find any of the Fords with the max payload package.
I got a GMC with their max trailering and payload is 2015. My trailer is 34"4' from hitch to bumper. 8200lbs CVW
I don't have any real issues with sway with my setup, but am using a 4 pt hitch. I've towed from central BC, through to Banff, Jasper area and also down the Oregon Coast. Never felt unsafe, just had some proposing issues between Jasper and Banff that I blame more on the bad frost heaves.
