Any time you hear that "my wife won't drive it." its not about the motorhome. Many women do drive motorhomes. It just takes getting past the mental block. Look at how many school busses and city busses are driven by women! Those are tougher than driving a class A motorhome. I have done all three!
To get around the mental block, going to a large parking lot in off times and feeling the coach systems out and/or taking driving lessons from a truck school or RV dealer or similar will end all reticence to drive. A number of men should also take those lessons!
