I picked up what looks to be an AMC-400 the other day off Craigslist for $100. It's unused so I figured it was a decent buy.
it says it has a 400lb. capacity, but I personally wouldn't load anything over 300lbs. Loading my bike by myself was fairly easy. I'll have to research how to get a duplicate license plate because the bike completely blocks the one on the Jeep. I'd also want to get some trailer lights to put on the back as well. I think Harbor Freight has some for around $20~.
I just loaded the bike up to see how it would fit. I would have strapped it down better if I was going to drive around.
Here's what I normally tow my bikes with.
