Weekend bike tours... 2 days, 3 days. I used to ride to work, then ride to a place along my route for Friday night, then ride further along the route on Saturday, and home on Sunday. When I had done local 2 and 3 day loops, I then drove after work on Friday to a starting point, a motel. Then ride my loop from there. I did lots of credit card touring. Then when you cut the cord, you just keep going. And you have plenty of experienced. It's fun to read when you can't be riding. I love, "Where the Road Ends", amazing book by a girl that rides from Russia through Mongolia, China, Vietnam, etc. Gutsy chick.
Also, I am 6' 3" and my weight has varied between 220 and 265. That weight and touring gear will no work on a regular touring bike. A Trek 520 will carry me, and ten or twenty pounds before the frame starts to flex, when it does, the steering becomes unstable. If you experience ANY instability in steering, first place to look is if your bike is overloaded. Money is not a problem for me, so I had three custom bikes made for me in different configuration to bear different weights. So my fully loaded touring bike is dead solid with me and 40 or 50lbs of stuff going 50mph down a pass... it is really absolutely solid.
I also, read a couple books like a couple guys that quit their corporate jobs and did the Northern Tier... so when I hit Rainey Pass on June 3rd, I was ready for the weather and grueling climb.
