If you are concerned with safety a school bus is probably the safest vehicle on the road. Each window has a steel frame that goes around the whole coach from the main frame on one side to the other side. They can roll over and still not crush. (50 years as a school bus driver) A class A is much easier to get all of the things you want. I have been RVing since 1969 and there are very few accidents involving RVs with injuries. I have had from my current Roadtrek to Mountain Aire, TT, and popups. Class A, B, and C. From my experience the Class C has the highest maintenance requirments of any with the constant work on the roofs. That cabover section bouncing unsupported gives great opportunity for leaks. Two Cs convinced me to be very cautious on them again.
