Use a weight distribution hitch or not?

While the equalizer might be over kill its by far once set up correctly one of the easiest hitches to use. provides great sway control and weight distro. my personal rule is you need wd and sway control when you get over 50% of your towing capacity. from what I'm reading your over. while its heavy you already have it and theres lots of good resources out there to get it set up properly on your vehicle. remember each vehicle is different as is each trailer so moving a hitch head between vehicles even the same model can require changes to your hitch head. I would recommend finding someone who is proficient at setting up an equalizer from scratch and either get them to help you or get them to do it for you.

or buy a ¾ ton and don't worry about it ;)
