Montypals: Not sure where I got this information…might have even been this list. But I recently purchased a trailer dolly. http://www.etrailer.com/Hitch-Accessories/Rackem/RA20.html One problem I have with my M15 is that the boat and trailer weigh 1600 pounds. Now, I'm not sure if it is the boat or trailer that are overweight since I have not had a chance to weigh the trailer separately from the boat. But the issue is that it becomes difficult to maneuver the trailer around my driveway by myself. It is always a strain, and somewhat dangerous. So, I had no idea that such a product existed such as a trailer dolly. But it turns out that a relatively inexpensive and elegant solution exists. The dolly has nice big wheels, and easily lifts the trailer from the receiver. Once lifted, I can move the boat around with great control, and quite easily. Just amazing. Wish I had known about this before. I can really put the boat and trailer with precision wherever I want. I just thought I would share this in case any of you are having similar problems. I would imagine that it would work quite well for you M17 folks who have to move a larger weight. Daniel Rich M15 #208 "Kestrel" danielgrich@gmail.com
