I won't be using the trailer with the Big Dummy. I really don't think so. That's my current commuter on this picture with the trailer.
I hope to use the Big Dummy for everything, from commuting and running errands to weekend rides and touring. I want it to become my main ride, a true car replacement. The commute is only 8 miles one way. When I go on a tour I shoot for 50 miles a day to have time for other things, although I've done 70+ miles a few times when I couldn't find the campground I planned to get to.
I'm 195lbs and I don't plan to carry more than 100lbs. The heaviest loads will be grocery shopping. On a tour I hope to stay under 50lbs for the cargo. I doubt I will ever push the BD even close to its limits.
