Cool (?) Bicycles: Cargo Bike Campers

Pictured here is the new spacecamper, usually a business for converting vans and such into campers, for cargo bikes.

I'm kind of undecided on this. It feels very convenient, unless you have an ultralight tent the weight of your bike, and your supplies and the tent and the bags and whatnot seems sort of the same as this stuff.

What do we think about the concept? Cool idea to incorporate your bicycle into your sleeping arrangement for trips or dumb playtoy?
