I'm still very new to touring, but I chose a trailer for this and many other reasons. I'm a real klutz and I didn't want to have to spend a lot of time trying to balance my weight. I once landed on my face because my bike was (badly) loaded. It's a trade-off, of course, because going uphill is slightly more difficult, but once moving, it's almost like the trailer isn't even there. One other downside is that it's easier to take too much "necessary" stuff!
