A few comments on equalizer hitches. I would hope that it will remove some fears about using them.
First of all they consist of 2 bars in tension between the truck and trailer. As such, they are a spring between the truck and trailer designed to off load the weight on the trucks rear axle and transfer it to the front axle, Nothing more. The spring torque is transferred through the hitch and frame, unloading the rear and loading the front. This reduces the rear sag and thus the load, it's only purpose.
I've used them on a 63 Chevvy C-10 with coil springs with no ill effect. I assume modern 1/2 ton trucks are built stronger. If your hitch and frame are sketchy, don't use them.
Now, I have a 3/4 ton truck. I tried equalizer bars, which unloaded the rear axle to the point that I lost traction. I removed them and all went well. The point is: if you don't need them, don't use them. Their only purpose is to unload the weight from the rear axle.
Some trailers use surge brakes, which uses the weight/inertia of the trailer to apply the trailer brakes, which require relative movement of the trailer to the hitch. Standard equalizer bars tend to resist this movement, so they are not recommended. A special type of equalizer hitch, using a roller mount to allow the relative motion is required.
Electric over hydraulic brakes can use standard equalizer bars, because they don't require the relative motion. Another advantage of EOH brakes.
