I also have the single Kendon. You made a great purchase. Used mine to tow my Harley from NW Louisiana to Sturgis and back. Hard to believe it was hitched behind my 4Runner. My gas mileage did not change towing the trailer. You are really going to like it. Big plus is the stand-up storage.
Here's one that just came up on Craigslist today here in Colorado Springs looks like a good deal? If someone looking and isn't to far maybe they can work something out. http://cosprings.craigslist.org/mcy/988932669.html
