If you have a power tongue Jack, the equalizer is very easy to use. I have also seen people have good success with the updated Anderson hitch with built in sway control.
Do not have a power jack. Those are very uncommon on horse trailers.
The design of the trailer is that there is roughly 6' of space in front of where the horse's front feet go, to accomodate the horse's head/neck and also some equipment. However, nothing heavy goes there as it's not safe in case of an accident, everything is secured.
I am guessing the tongue weight is 375ish empty and about 420 fully loaded. This particular model is actually the shorter one that produces more tongue load. These are also available with even more storage space in front and an 18'6 overall length, tongue weight there is about 480 fully loaded despite being at least 600lbs more trailer.
Horse trailers are a little different than TTs-- there is only about 3' from nose to hitch to pop something on there, at best maybe I could put a battery in.
The trailer looks like this, except it is 18" longer between the doors marked and the nose radius begin. The axle position (dual axle) is marked by the yellow bars, and the horse stands between the rear bumper and the front doors--so there really is not much horse in front of the forward axles except for the head/neck.
