We have a Bushtec Turbo 2 that we have towed for about 18,000 miles. Reserched trailers for a year before buying one. Bushtec is not cheap there are many that are less money.
Mine weighs 125 pounds empty, larger tires turn at the same speed as the bike. Have stage 1 TC88 not had any problems with pulling the trailer. Yes it would be nicer with more power but still works fine. Takes some getting used to but the more you tow it the less you notice it is there.

 

+1 for Bushtec. Had mine for years... NEVER had an issue. Of course, also have the 95" upgrade from the factory.

 

On any long trips we tow a Bustec behind our UC. I normally ride 2 up with my son behind me and my wife on her own bike. The trailer gives us the flexibility to have additional riding gear (warm weather/cold weather) as well as keeping the bike from being loaded down. With the trailer loaded you have to think a little more about passing and stopping as well as recognizing that a decreasing radius turn off an interstate will give you some cause for alarm if you forget the trailer and take it too fast. Don't ask me how I know that one - glad that the shoulder of the turn off was fairly wide when I needed it the most.
