If this hasn't been posted before, I thought ya might get a kick out of this video showing RV's from 1937. Evidently these kind of short films were financed by Chevrolet.
You can see more, if you click the full video link below the video window.
Hope ya enjoy seeing it as much as I did. There are really some neat looking RV's from that era.
