I have towed an American Legends trailer behind my 99 Road King for over 25,000 miles, without a problem, wouldn't think of taking a camping trip without it. It allows us to take a tent you can stand up in to change clothes, two cots, two chairs, a cooler, and lots of other little camping perks like lanterns and water jugs. What I liked about the American Legend trailer was the styling, it has fenders similar to the FL front fender, and tail lights and turn signals nearly exactly like HDs. It has an internal spare tire compartment, that doesn't reduce capacity, and will also hold a few tools and oil. The tire used is available at any WalMart, so you could travel a lot of places without a spare. I paid extra for the rotating hitch, and have never pulled a trailer without one. You don't know its back there until you pull in to park or get gas, you have to remember to pull a little wide around things. It will lower your mpg, and it will push you a little in a panic stop, but I think the extra carrying capacity and keeping the extra weight off of my bike is well worth it.
just my two cents,
