I started this project with a web search. I figured that these trucks must have a Class III hitch available on the aftermarket somewhere... and got several hits in Australia. Shipping something this heavy was going to cost an arm and a leg... but I got the inspiration I needed. My neighbor is a strong welder and offered to help... he and I do a lot of labor/skill/knowledge swapping on projects for our homes and cars.
There are 5 captured nuts (M10) on the outside rear of each side of the frame on the FJ75. So we started there with some plates that would bolt in. Here we are getting initial fit. We ended up slotting the holes so we could get all five to thread.
Next was a cross member to tie them together and he had some scrap heavy-wall pipe that fit the bill. So that got tacked in once we checked measurements and alignment.
Next, the receiver tube and a plate to bolt into the face of the rear frame crossmember. M12's that hold the factory pintle were placed to get good alignment on our holes in the plate.
All tacked together...
He'd do some welding and then bring it back over and test fit it. We knew that the welding up would shift/warp it. And it did. So prior to the final weld he made some adjustments and also fabricated a jig to fight the warping. In the end, we got it done so that it installs/removes relatively smoothly... it's just heavy and awkward shaped and it takes two people plus a jack.
With welding done I sprayed a few coats of John Deere Blitz Black.
Mounting...
Installed...
You have to have the OEM Toyota receiver cap of course! I also wired in a 7-pin connector for the pop-up camper. It doesn't have brakes yet but the trailer is pre-wired for them and it's a very straightforward upgrade to electric brakes (new backing plates and hubs).
And lastly, I really wanted to still have the aluminum step. I had an older one that had gotten tweaked so I cleaned it up and did some cutting/grinding to make it fit around the hitch. Worked perfect.
With a 6" drop hitch I get a perfect tow height for the camper. The troopy accelerates slower with the trailer in tow, but cruises just fine. The whole assembly tucks up very nicely under the truck and even those massive side plates didn't really impact my departure angle at all. In the San Juans I only hit a few times... and it was the stupid pintle insert that dragged, not anything from the actual receiver assembly.
