Well I have always thought that if it did not fit on the bike, you were taking too much stuff.
If it just you on the bike, there is no reason for you to pull a trailer. A RK with a rack or a tour pak will haul more than enough stuff for one person. If it is you and the OL then take fewer clothes and use motels, but you can fit the camping gear if that is your choose, just buy back packing equipment that is compact and light.
Washing one load of clothes every 4 days is the same as washing two loads every 8 days so taking fewer clothes is of no real impact.
I do have friends that pull trailers and on one occasion during a panic stop, my friends trailer jack knifed slightly causing the bike to high side and it threw his OL off the bike. She was not hurt, but it would not have happened without the trailer.
On another occasion, I saw the end result of an accident that involved a Gold Wing rider pulling a trailer. It was on a straight section of road. It was a single vehicle accident, only the GW was involved. We got to the scene as the ambulance was leaving, without the lights on. The GW rider did not survive. I did not see what happened, but I have to believe the addition of the trailer was the determining factor since there was not anything that the rider could have hit at the scene. Something happened causing him to go down, and between the bike and the trailer, he got caught up in the mess. It could have ended up the same with just the bike, who knows, but his odds would have been better without the trailer.
Pulling a trailer adds a degree of danger I am not willing to accept. I would add a side car to my bike before I would pull a trailer.
Keep in mind, pulling a trailer increases your stopping distance, requires addition maneuvering space and adds more things that can go wrong. On more than one occasion on road trips, if I had been pulling a trailer, I would have had an accident because of cagers and animals and the increased stopping distance. I was not speeding on any of these instances, just cruising along, enjoying the road and the scenery. Sh!t happens.
I know people do pull them without incident, one of my friends has for many thousands of miles without problems, and many will say they are safe if you take proper precautions and that is their decision and I respect that decision, it is just not for me.
If you do decide to pull one, make sure you know the trailer hitch load rating for tongue weight and maximum pull weight and the weight of the trailer and its contents. Load it evenly and practice with it loaded before the trip.
What ever you decide, I hope your road trip is a safe and fun one.
