I'm using the Andersen with our Mobile Suites. Love it.
Hitching up to the ball is not an issue at all. Very simple. The only posts I've seen about how difficult it is is from people who don't have the hitch.
You have to raise the trailer a few inches higher to hook/unhook than you would with a traditional hitch. Not difficult.
If one is troubled by the safety chain issue...get them. Andersen offers a kit. I have it. Again, some are making a bigger deal out of this than is necessary.
If I felt there were any negatives with this hitch I would share them. I would never advise someone to get something just because it's what I'm using. If I didn't trust this hitch I would toss it and get something different. At this point, I have no desire to go back to a traditional 5th wheel hitch.
