I would definitely use a weight distribution style for the loads. Too, with the axle issues, make sure to not overload and maintain fluid changes and brakes, yada, yada...Anyway, I went to Autozone's website and pulled up a couple different types. This was for a pickup, 2wd. I would look at the hitch frame you have first, and then take a trip or browse online for similar shaped hitches. Without looking to see how far back the frame goes and uniformity, I am uncertain, but hitches are usually hitches, they usually just match up to different frame shapes. You have a Toyota truck frame. Too, you can further take to say a Meineke and have them weld it to the frame, rather than bolting only. Hope this helps.
