A friend was making one. I helped with his build and design we based it off a trailer camper. After seeing his I want to minimize mine to finish my bicycle journey of America's Lower 48 States. I had the camper for almost 5000 miles and 4 months thru I think it was 6 states. I did a total of 22,000 miles on my entire journey for 3.5 years, including healing time from my accident.
