Hey Bob, thanks for the comments, but the real inventor is inmate junkcollector who acquired and set up the van in the first place. All I did was find a way to mount the chock. I am grateful that he sold it to me. I got a new set of spark plugs, and a new set of tires, and I'm just loving it! I understand the concept of the little sign that some people put on their bikes, "If you see this bike on a trailer or in a truck, call the cops -- it's being stolen!" Another one that is popular among people who actually ride their bikes to the Sturgis Rally says, "Hey yuppie, trailers are for boats!" (Do people still use the word "Yuppie" ?) Yeah, motorcycles are meant to be ridden, not carried, but there are a number of valid exceptions to that rule.
