I travel around the USA on a Honda Goldwing. Last summer I was on the road for 3 months and traveled 13,000 miles. I realized that a cargo trailer would make my life easier, but being retired, I didn't want to pay $3,000 or more for a trailer. I was at a hot rod show and saw a few teardrop trailers behind hotrods and thought that it might be fun to build one to tow behind my bike.
I took one of the plans on this site and am building to 1/2 scale. I'll post photos as I go. Thanks for all the helpful info.
