So I got my hitch from Bill and had it installed the next day
Mind you, it didn't take 30-45 min to install - it takes half an hour alone to take the diffuser off and keep track of all the screws but it just might be me...
I really like its design, the instructions, and the care taken to pack it safely. One suggestion I might have is for the fish wire to be threaded on both sides in case it gets disfigured on the first bolt as it did in my case... One small misalignment and you're in big trouble... Having the other side available for the second screw would have saved me many hours...
So again, very cool for carrying the bikes and the quick release feature is great. I've noticed that Curt and the above-referenced Torklift now have their own solutions, all in the same price range. The advantage with those two is theoretical potential for safer towing (obviously not-recommended) but Bill's solution seems to be lighter, more stealthy (especially when released), and easier to work with when attaching and taking off lighter accessories like the bike rack for example. There's no need to mess with screws - just pull the cable, drop everything, and you're done.
Any other pros and cons among different hitch options that you guys can think of?
