I'm really getting quite the kick out of all these comments. I guess maybe I've just been around too long. I remember when seat belts were optional and not even a standard in all vehicles. I remember kids riding in the back window. I remember riding in the back of a pick up truck. I remember see-saws, merry-go-rounds and dodgeball before we decided all was too unsafe. Now, don't get me wrong, seatbelts were a great addition to riding in high speed contraptions like cars and riding in the back of an open pick truck is agreeably dangerous, but come on people. Suicidal to ride in a 5th wheel? Elevator doesn't reach the top floor? I've survived much more dangerous things than riding in the back of a 5er and I have no more issue with it than riding in the back of the MH. Be smart, don't be running around, have things strapped down, etc.
Take this with a grain of salt though, I'm one of those crazy bikers that doesn't wear a helmet either because rather than believing absolutely everything that's forced upon us, I ride and I understand the importance of being able to see what's coming. The helmet greatly impairs my peripheral vision, subsequently reducing my ability to properly drive defensively. Plus, it creates a lot of pull on my neck causing pain long term in my spine. Then there's also research that shows most motorcycle accident outcomes are not determined by the lack or use of a helmet. So ya' know... The more you know...
