I recently got a little lucky with a trailer. It's not a Kendon and it's certainly not new. However, it's very functional and I like it. It's a single rail trailer that when you disconnect it from the towing vehichle and uncrank a strap, the track drops down to ground level. Once your bike is secured in the trailer track and tied down, all from the safety of being on the ground, there is a crank that you turn to raise the track. Once it's back up, you insert a couple of pins to secure it in the up position, reconnect the trailer to the tow vehicle, and away you go. The trailer is a mid-80s model, but other than the paint being a bit faded and the strap that you crank being a bit worn, it's in pretty good condition. I've already been offered more than the $750 I paid.
My very good friend Roger White has bailed me out many times with his fine 3 rail trailer, but my new-to-me trailer must weigh only about 1/2 of what his does. I towed a bike to TriSTAR since I had so much to carry, and while it was not without any impact on the vehicle's fuel economy, I was surprised at how little effect it really had.
The brand name of my trailer is Easy Hauler and was manufactured in Dallas, TX. I can't find any references to the company now, so it must have gone belly up.
