I've owned two uni-go's I like them a lot, they where made in new zeland at first and for the last (I think) 3 years they've been made in Cincinnati Oh. the guys making them now are really good guys to deal with. I've been talking with them about being a dealer for them.
They do carry every thing my wife and I need for a week trip and it does take a lot of wieght off the bike. And as stated before the trailer can be rolled into the room and your free to take the bike for a cocktail with out fighting to back it and park it. I've even taken it into an elevator in Daytona (you get a few looks but how cares) The only draw back is if you over load them (and I do meen over load, tent, 2 blowup matreses, 2 kenmet chairs, tool bag, wool army blanket, 2 camp pillows, sheat, 2 pair of moccasins, small rug, air pump, wife's gortex rain suit and a hafl weeks bag of clothes) and get over 85 mph my bike starts to wobble I've just installed the Ride Str8 on it so I'll see if that helps.
Here is some picture if mine with the classic rear fender
