Thanks for your help, Diane. I had a pole made that attaches to my single 4-wheel carriage. Basically it is a drop pole (since that is the easiest for converting a single carriage). When attaching a pole to your single carriage and pulling with a pair. Make sure you are not putting to much stress on the fifth wheel. The fifth wheel? Hmmm. I have a two wheel cart.. There has been much discussion in the past on driving a 2 wheel carriage with a pole:-) probably information in the archives. Thanks I will search them. Karen
