Wife wants to move to a Class A, or C - bigger

I personally know... or knew... a few people who died recently in a big bus-type Class A, when it rolled after a front tire blew out.
The rig was full of a whole family. I believe that being properly seat-belted in passenger compartment seats would have changed the outcome for the better.
This is part of why I’ll only carry a camper on a dually anymore. All my SRWs just felt like they’d roll in a blowout.
