I put up a post a few days ago that showed a guy with what looked like a small pickup truck camper on a bike. The post wasn't meant to be serious just adding a little humor to the day which is obvious from how it is written. Well, if you look at the comments you'll see someone who is trying to raise money to build a bike camper. They have a nice website and nice renderings but no comments on weight and it has components that would make you think it would weigh at least 100 pounds. No actual construction, just renderings.
