I won a great condition M105A2 trailer (judged by pictures, sight
unseen but the wheels look inflated and it looked good). I bought it,
because it was cheap to me (really, I bought by accident) and has nice
stake sides and top, which is what I want. I bid only for the sides
and top.
I was able to rescue the pictures from the govliquidation
website. Here they are.

As you can see, it is in great condition.
Except for the mostly unreadable weight and dimension data plate...
The label sucks. I added some info to that webpage with NSN
information. It is 166 inches long and 83 inches wide. I would guess
that it weighs 1,700 lbs.

The plate and your data seem to indicate a coupler height range of 20
1/4" - 34 1/2", and a GVWR of ~4,700# which would make the trailer
suitable for use with any full sized pickup.
Brakes, the air-hydraulic drum brakes on the trailer should be able
to be converted with the addition of a hydraulic brake actuator ($140 at
Northern Tool), to provide self contained hydraulic surge braking and a
normal 2" ball hitch, without any modifications to the existing axle or
suspension.
This is pretty cool. I now wonder if I took the optimal approach to
making my own trailer.

Multiple approaches, each has benefits / drawbacks.
I've not personally seen one of these trailers up close, so I'm making
some educated assumptions on the brake system. Since your spec indicates
air-hydraulic brakes, and from the pictures I don't see any sort of air
brake cylinders on the axle, I'm assuming that the axle has hydraulic
drum brakes and there is an air-over-hydraulic actuator buried under the
trailer somewhere. The assumption is you can ditch the air-hydraulic
actuator, and plumb the brakes to the noted $140 hydraulic brake
actuator coupler, and of course mount the actuator coupler in place of
the pintle / lunette eye.
