Since you're also looking for how people like the Andersen hitch, I'm one of those who was really dissatisfied and replaced it, admittedly with a hitch costing twice as much, and weighing several times more. You have to be careful discussing likes, or dislikes though because for some reason folks get emotional both in liking, and not liking the hitch. It's kind of comical really in that a hitch is simply a very basic piece of equipment. You can look up my post regarding the issue from a few weeks back.
What I didn't like about the hitch is that it damaged my pin box, and I had concerns that continued use without further intervention would lead to damage to my truck bed. I had made and tried inserting some shims into the truck bed for a short time, but removed them because the increased the occasional pop I would get out of the hitch in some conditions (Not every time I towed). I was also disappointed in the response, or I should say lack of response by Andersen to the damage done to my 5er. At first they didn't respond to my e-mails, and initially never got back to me after phone calls, even though it was an issue they were familiar with, and had shims to remedy.
The above said, most of the folks on the internet seem to love the Andersen Ultimate. Surprisingly, since I started having issues with mine, and looking at the hitches in use by others I've found several folks that are quite unhappy with the hitch, and even learned I work with, or should say interface through work two folks that have quit using the Andersen because of issues they were having with it. Personally I find it surprising, as generally you see lots of negatives on things when you look them up on the internet, but don't encounter many folks in person having issues. Good luck with whatever you end up with, and more importantly, get out there and have fun with it.
