There are plenty around, some of them are probably on a different side of town though if you havn't seen them. I know of 2 dummies, 4 or 5 xtra cycles and one lucky bastard even has a stokemonkey (which works amazing by the way)
When I first built mine i ended up hauling about 80 lbs of rock just because I could and it handled the load great. Yesterday I took the long way and went grocery shopping with it. Tomorrow I plan on taking it to do laundry.
I even decided to forgo riding my mountain bike even after fixing a bunch of stuff on it yesterday so I had time to ride the xtra cycle more.
You will love yours for sure. I know mine has already saved about 25 miles on my truck and I have only owned it a week.
Hope to see ya on the road sometime.
