Harley-Davidson will VOID any warranty you have if you're towing a trailer. But more than this, towing a trailer (which doesn't have brakes) is a good way to have your bike over-run and jack-knifed if you need to make a sudden, hard brake.
Call me whatever, but I won't ride with anyone towing a trailer on any bike.
I guess he's moving, I have moved several times in my life with less than that and it was all my earthly possessions. Yep looks like an accident waiting to happen, I give the trailer guys a wide berth.
Dont knock the guys who use a trailer, This guy is just lacking common sense, I had a bushtec trailer for years and pulled it on some great road trips and never had any issues mechanical or saftey . last year I had an issue with the ABS on bike while in Kentucky, rode into a dealer with the trailer attached, they fixed the problem under warranty and never said a thing about the trailer.
