Fred, as you have probably figured out, there are lots of hitches out there and just as many people who like theirs. Properly set up, most brands can and will do a good job.
Andy is not a fan of the Equalizer especially when using a very heavy duty PU and oversized bars. If you get too rigid, damage can be done to the frames and skins of an Airstream. I respect his experience in this regard but by mitigating some of these factors, an Equalizer is a very decent hitch.
For me it came down to money and ease. Like you, I have a half ton truck towing a 25FB. The suspension of the truck is forgiving and I am using 1K bars and have them dialed in "lightly". I run level and have never had any issues with sway or any of those other things people talk about. I suppose if I did have issues, I would look into a Hensley or a Pro Pride.
What I have works for me. I can hook up on level ground, uneven ground, in the rain, in the dark and in bright sunlight. Actually bright sunlight is more of a challenge. Dropping the hitch on the ball sounded much easier than backing the stinger into the receiver.
If you are planning on moving up in size, you can just buy another hitch. Buying two will still be less than the outlay for the Hensley/Pro Pride.
