"I am interested in a trailer with folding front and rear axles and with collapsible/detachable soft top. That way I can also tuck the trailer in the garage (with the KR parked separately) thanks Bobby" Look here for ideas: http://trailerinabag.com/products.php
Saw this product while working this year's Bike Week (no I did not get to ride this year). The last coming soon trailer is a flat trailer with 2000# capacity that breaks down and can fit into a bag and be carried away. The guy's wife (owner and wife) broke the trailer down after getting the bike off with no special tools and stored the trailer in the back seat of the truck king cab! With a little thought and a rack for the wings, one could do the same for a KR transport trailer. Or use a converted Airstream RV trailer as one builder did. This is the same builder that designed a coupling fitting that aligns the wing for easy attachment, and a tray to roll the wings onto and off the trailer. Colin Rainey N96TA
