Trailer: Open or Enclosed
We've hauled our LTs in both open (a Kendon stand up double) and closed (Haulmark Lowhauler RT) trailers.
The Haulmark was far more secure; the bike stayed clean and there was room to put our riding gear in the trailer rather than in the car.
The drop down rear door made loading and unloading fast and easy - just ride it in.
It towed like a dream - even in high crosswinds and the electric brakes on all four of the trailer tires let it stop on a dime.
However, the Lowhauler was still high enough to block our rear view which meant we had to use fender mounted rear view mirrors. And, the wind resistance and considerable weight of a 8 1/2 wide, 20 foot long trailer meant our gas mileage (Mercedes 350ML) went down when compared to hauling the open Kendon.
The Kendon was light weight, very easy to tow, offered a good view of the vehicles behind. It was easy to store - we just removed the tongue and stood it up in the garage - it didn't take a lot of space.
However, loading and unloading the Kendon can be a bit scary because you have to ride the LT up a narrow ramp and your feet don't touch the ground until you get it all the way onto the trailer.
Plan on washing the bike when you arrive because it will get dirty - it will also get rock chips from the stuff thrown up by passing vehicles.
Don't put a cover on the bike when towing using an open trailer - no matter how well you secure the cover it will move (flap/vibrate/balloon) and at those move spots the paint will get scratched.
Regardless of which trailer you buy check your insurance coverage. Many carriers don't insure the trailer at all, others may insure it only when it is connected to the vehicle.
Given a choice and provided your tow vehicle has the capacity to handle it - buy the enclosed trailer. It's harder to store but so much nicer to use.
