Another vote for Bushtec here, they're expensive but worth every penny.
The LT is powerfull enough to tow anything you want to,
the heavier the trailer the more you sacrifice performance.
My first trailer was a Bunkhouse camper, great camper but much to heavy (225 empty) add to that just about everything imaginable you can stuff into the cargo hold (We had a 5000 btu air conditioner) etc. etc.
My wife and I took it on a 3 week trip from Florida to the U.P. of Michigan and back and I sold it.
Man I hated pulling that heavy ass trailer around.
Now I know this statement is going to bring out the ones that say: I've been pulling a Bunkhouse, Aspen, etc. etc. for years without any problems blah blah blah.
Hey I'm happy for you, I hated the damn thing.
Next I got a Bushtec Turbo (125 empty) with air suspension,
this thing handles great, can't tell its back there.
What really impressed me was when while going through a grocery store parking lot over the speed bumps, I felt the front wheel go over, then the back and was waiting for the whiplash jerk my Bunkhouse used to cause going over the speedbumps and it never came,
the Bushtec's air suspension is that good, sweet.
Here is a link to a trailer towing forum for all kinds of bikes,
you'll find information overload and opinion overload just like here, enjoy.
