I find a lot of these bike type things are great in theory. I have a low speed electric scooter. In order for it to legally be considered a bicycle and except from licencing and insurance, it needs to have pedals. At 250lbs, the bike is impossible to pedal much more than 10-20 feet without it just wearing me out. I wonder how possible it is pedal one of these campers.
More practical than a complete camper would possibly be a little bike camper with a tent and seriously light gear and be in amazing shape.
