I am not a "Scaredy Cat" by any means, having ridden and raced motorcycles since 1968. The primary reason we sold our Class A DP was that I never felt safe being the "First person at the accident", with only some plywood and fiberglass between me and the crash site.
While our coach was well constructed (Alpine 40MDTS) there was literally only plywood and fiberglass under and in front of my A**. I constantly worried about a front tire blowout that could shred the tread off and have that 100+ lb road snake take off my or DW's legs.
Went "Super C" on a Freightliner chassis and all that stress and worry is no longer there. I know that in the event of an accident we are well protected.
