The year before last our friends who were traveling with us across the U.S. at the time totaled their Class C via a bus from a cross-street hitting them head-on on the side wall just behind the driver's seat.
Nearly everything inside the coach area came loose and/or flew apart - from BOTH WALLS of the coach. I hate to think what would have happened to the bodies and heads of anyone sitting in either dinette seat - seatbelts or no seatbelts.
Our lifelong friends - the driver and his DW - fortunately came away with only bruises. They rented a van, we helped them load it up with as much of their personal items from the RV as we could, and they drove across the country back home.
Nobody should be in Class C dinette seats if hit from the side!!! Probably a head-on or rear-ender would be different, but still potentially as dangerous from flying microwaves, refrigerators, wall cabinets, etc. .... which all went flying during their accident.
After seeing their mess, Class C coach areas are a LONG WAY from being anywhere near as safe as the steel clad cab area.
