We installed a Fastway/Equalizer Trunnion (square bar) weight distribution hitch. We had to get a longer shank because the one that came in the box did not go low enough. Trailer coupler height from the ground to the top of the coupler is only 16 inches. Top of truck receiver is 18". That's fine if you don't want to use a WDH.
I prefer to use one with my Tundra (1/2 ton) to haul my new Jamco 2 horse slant bumper pull with dressing room. It is 14 ft long, weighs 3600 lbs empty and has a tongue weight of 700 lbs empty.
The problem is ground clearance when installed. I only have about 3 inches clearance! I have looked at other makes of WDH models but they all have about the same depth.
The only other option I can think of is to get a welding shop to add bars to the top of the trailer frame and then mount a new coupler. My old Moritz came like that from the factory.
