I bought my Rapid-Hitch in 2006 for my move. Paid about $275 for the hitch, the 1 7/8" ball and the locking pins. When I got it I thought it was so pretty I was going to mount it on my wall. The main reason I bought it was it is much lighter than steel. I have arthritis in my hands.
The reason I'm posting though, is don't do what I did. I used it in December 07 and left it in the receiver until the spring of 08. I live in the rust belt. I needed to take it out and I couldn't. The steel pin that holds it in the receiver welded itself the aluminum hitch. My brother and I got it out after a very long time. We had to use my neighbors drill press to drill the steel out of the hitch. I take it out now after each use.
