Gonna pick up a B&W 3", 7.5" tri-ball hitch. Will be towing an Intech Discover (20" ball height, GVWR 5200lbs) and a 7x14 utility for motorcycles and whatnots. Was going to get the 4.5" as that should work with a 20" ball height, but the utility trailer would be tilted. Hopefully no to little drag, but we shall see. Thought about doing the 2.5", 7" hitch, but it came down to .5 in vs using a reducer and increased rattle.
Was going to get a weigh safe, but I'll never come close to max tongue weight on the F350 6.7 any time soon.
Was not going to do the tri-ball, but will need the 1-7'8" if I ever want to rent/buy a chipper.
