Ric, I just purchased a Hitchrider http://www.hitchrider.com/trikes.htm.  I took my trike to Mississippi and it traveled really well.  With the locking pin on the receiver, it didn't sway at all. My brother has a friend with a Davert and he travels all over the south with it.  He loves the Davert, but I wanted a rack that tilted up against the car when not in use.

How long did it take to arrive and was it already assembled or did you have to put it together????
