The title of this thread is Class A Safety. Here's something I know: For a motorhome to be safe on the road, it must FIRST be in the hands of a good safe driver! I know a great deal about what it takes to be good driver and also be a safe driver. But, this thread quickly turned into a discussion about the quality of the Design and the HANDLING character of motorhomes. Motor vehicle chassis dynamics is something I studied. And, at age 83, I've had plenty of time to learn much about motorhomes.
I would like to help the OP, therefore I will attempt to make contact with him by private message.
