You can definately tour fully loaded on a Jamis Aurora. I have one, its a 2000 model, and have taken several fully loaded camping trips with it. It can handle the weight.
I am in the process of switching the original brake/shifter levers for bar ends shifters and separate brake levers as I found the original brifters to just be uncomfortable and cheap for me. They have worked fine, but I want a different setup now. I have always liked the Auroroa for a touring/commuting bike, the geometry really feels good to me.
