Wife fearful in Class A

We've joked lots about my wife being in the "Catbird" seat and that she is my N A G A V A T O R, but the problem is very real.....It is scarey at times sitting in the right hand seat, especially on narrow roads. We have a Chevy chassis which is on a narrow wheelbase (compared to Ford) and the passenger is almost outside the actually wheelbase. I try to drive slower and stay closer to the center line. Of course, the comment I make is that the drivers coming toward us have larger than normal eyes as we approach them!!! Just stay between the ditches....and you'll be fine.
