Trailer comes off at 75mph
This maybe a simpler solution.
I took the hitch pictured below and ground a bit of metal off the top latch so it will close and lock over the top of the coupler.
I came up with this after consulting with Murf about the negative loads placed on the hitch when operating the dump trailer.
The side benefit is that it will certainly keep a firm grip on a coupler at highway speeds and is cheaper than replacing the coupler and all that brake stuff.

Well I think there is a point of discussion here. I tried for a couple of years to rig up a trailer that would carry a 225 gallon water tank behind my tractor.
Everything I tried, including a steerable wagon running-gear, pushed the rear end of the tractor into a jack-knife on downhill turns.
In math terms, that was a 400 pound trailer with a 1875 pound load pushing a 3500 pound (ballasted operating weight) tractor sideways into the sagebrush with great regularity.
I finally solved the problem by going to a water tank half the size.........

Hey Murf.... brakes? Maybe, maybe not. I drive around in low range at just about the same speed whether up-hill or down. Not sure how the brakes would "know" when to activate as I use the HST for stopping, not the tractor brakes. Manual switch? Maybe.... but by the time I would think I need it I am in the ditch, so to speak.
I suspect the loose sand and gravels I was driving on played a part in the towing instability.
EW.... I agree that gravity is the other wild card in this game and now that I think about it, I can transport my empty flatbed @ 2000 lbs and the unloaded dump trailer which is even heavier, down the same hill quite safely. So there must be some load geometry in play. The empty trailers present loads that are much further back than the water tank.
The water tank set-up was about emergency fire fighting during our summer lightning season, so the whole thing might have to do some limited brush busting to get on scene.
If I could have solved the problem with the trailer I would probably have run into traction issues on the sandy uphill pulls.
So I split the load. I figured 225 gallons might buy me some time until the big boys in the yellow truck get here, so I currently carry 125 gallons on a two wheeled trailer and a 65 gallon tank on the front forks.
Close enough.... and enough weight on the front axle to boost the traction on the sand dunes and gravel........
