We have a 2012 Ford F-250 diesel and have had no problems pulling our fully loaded 385BH. Ours arrived in May of last year. I did add "air lift bags"
in the back to help to level out the load and the bed. We have pulled ours throughout the North GA and North Carolina mountains as well the Carolina coast, all over Georgia and throughout northern and central Florida. I am typically getting around 11.5 mpg. A little less in the mountains and a little more through south GA and Florida.
