I am building one. Got a good deal on a frame and will be here in a couple weeks. For me, with kids and a lot of errands that generate loads that I cannot just carry on a regular tourer, the Big Dummy makes sense.

We have horses and sheep. I need something that can haul a bale or 2 of hay and you can tie 50lb feed bags easily.

I can also use it to transport a kid to gymnastics practice six time a week (my daughter and son go on alternate days). I am really looking forward to one. I may not go carless but using less of it is my goal. These bikes are incredibly easy to handle. and just like a good diesel pickup, handles better when loaded.
