RVs or motorhomes have been around since the early 1900s, but how exactly has camping and traveling changed since then? In Elkhart, Indiana, we travel through time at the RV/MH Hall of Fame to see the evolution of RVs, trailers, and motorhomes from the earliest models to the modern types. Next, we visit Indianapolis, or rather the catacombs that lie underneath the city. Lastly, we stopped by Mentone to see a 3,000-pound egg.
