Child safety in a prevost

One post mentioned the law of physics, I'd rather apply the "Law of the Lugnuts", the vehicle with the most lugnuts win. In my mind as a long time RV vacationer (not science just an opinion)the danger to the child or any passenger are the flying objects from unsecured items. You know, the toaster, the coffee pot, dishes, all those little things we forget to secure. Naturally I would not want to put an infant alone on a coach, even in a brick home, as they might roll over and out. When the twin grandkids, now 6, were only infants, we put them in car seats secured only with the couch seatbelt. There is no testing or data to show this is safe or secure, it just kept them in place. Now they are allowed to sit at the table, even walk to the bathroom while we are in motion. I believe highway tests prove seat belts keep you from going into the windshield and being ejected from the doors...neither apply in a large motorhome. Be safe, love your family, protect them every way you can and always be there for them. But you are providing a great deal of protection by putting them in a Provost instead of a smart car with a seatbelt.
Happy Trails.
