We have two of the condor chocks. Usually one is set up in the garage in case you want to drive a bike into it for working on the bike, one is folded up on the garage wall. If we travel and need to haul a bike, the chock is easily moved to the desired hauling vehicle or trailer.
The comments about whether one trailers or not, have nothing to do with the value of this accessory.
I wish I had a trailer for hauling a bike or three everyone once in awhile. Actually, the wish for one has come up at least once a year for the past three years when wanting to do and yet one more meeting with our CVO friends. I am happy for those who have the health and constitution to be able to ride 20 hours a day, day after day on a cross country trip. For my husband and I, we are very happy when we can roll 800 - 1000 miles a day, one after another. We can travel much farther in a four wheel vehicle than two. We tend to drive to our destinations as well, but that is mainly cause that is the only way we have. When we both retire for good, a trailer is on our list of desired additions. Just not sure if we want a trailer to haul the bikes or a trailer to haul behind them.
