I don't believe I will have a head-on accident, so I'm not much worried about the "safety" aspects of my Class A.
Sure, it CAN happen, but I really don't think it will. It hasn't since 1958, and it isn't likely now.
Unless I hit a deer or an elk. But then, the animal will be below the floor, so I'm not too worried about that, either, and I rarely drive the coach after dark, which lessens the chance of an animal accident greatly.
Now, having said all that, over the years I have owned a camp trailer (not self contained); a Travel Trailer (self contained); a 27 foot class A (terrible floor plan); a 32 foot Class A (nice floor plan, but GM 454 engine); a 29 foot Class C (Ford 460 engine, not bad); a 32 foot Class A with one slide out (VERY nice!); and we lived full time in a 32 foot triple slide fifth wheel (having the washer dryer combo was GREAT!).
AND, just to keep things interesting, I had 6 foot, 9.5 foot, and 11.5 foot truck campers.
We are very happy with our current Class A. We have no desire to go back to any of the types we had before.
