There was an article out on the Internet by Bob Gummersall dealing with frame rail vs. semi-monocoque and monocoque constrution that I read back in the 90's and was my introduction to quality RV construction. These pictures illustrate the point he was trying to make, most motor homes are not built to survive an accident. I'm glad that I own a Newell and know that in case of an accident I'm surrounded by quality construction that will protect me and my loved ones.
