John,
I am pulling a 25FB with my half ton Tundra and I use an Equalizer hitch with 1K bars. It works great for me. I am a fan of the Equalizer but there are some issues out there you need to be aware of.
On the Airstream forums, the Hensley and its sister the ProPride (I believe) are the consensus go to hitches. If cost is no issue than you should look in this direction. If you go with a more traditional hitch it is very important to get the right sized one. If you "over hitch" your Airstream the forces applied can actually damage the trailer. People can easily pop rivets and even, in some cases, crack the skin if the setup is too rigid. If you have a very stiff 3/4 ton truck you still need sway control but the need for weight distributing might be less than if you have a sissy little half ton like mine.
My Equalizer is dialed in nicely. It is easy to hook and unhook and the trailer follows nicely behind the truck in all kinds of conditions. I did not go in the Hensley direction for two reasons. First was the cost and secondly was my perception of the difficulty in hooking up. You don't just drop the trailer on the ball but you have to drive the stinger into the hitch. People who have them say it is easy once you get the hang of it but others say that it is a challenge especially when on uneven ground.
Good luck, you are going to like the Airstream. It will be an unbelievable experience towing if you have towed a conventional trailer before. Oh, I am also a big fan of the Prodigy controller.
