Yes. Also referred to as a weight distribution hitch.

Oh the good old wd hitch.....my favorite...

On the MPG topic- tuners, airboxes, big exhaust and such will probably bump your MPG. They'll also make it awfully tough to get a warranty repair if you smoke your motor. Ford gets $13,000 for a new 6.0, installed. I can buy alot of diesel for thirteen grand.

trailer for donzi 38 weighs a lot more than 1500#, even aluminum

How much would the trailer weigh? Even 2000lb would still keep me close to 15000lbs.

Chris is right, you are talking about the absolute limits on towing capacity and safety. And as he said, it is not you to worry with, it is the idiot who will force you to swerve and try to regain control while next to the mini-van that would worry me.

If you want to haul that much weight, go to a 5th wheel trailer, or duals, anything less is simply not safe enough for any serious travel.

I don't think you can get tow limits of 15K with a tag along trailer without going to a dually. And to be fair you rally want the dually for that kind of weight.

my 28 alum tandem trailer wioth dual brakes and a spare weighs right at 2000#....

I wouldn't even think of towing 15,000# with an SRW truck, but that's just me..

Dually.

The training wheels do so much more than just add GVWR, stability is SO much better in a DRW.

Only reason I would go back to a SRW is if I towed nothing at all.........

(besides, you get used to the extra width, nothing to it)

The gross combined weight rating on an single rear wheel F250 is only around 23,000lbs. the truck is 7, the trailer is at least 3, that leaves only 13,000 for the boat.
