Sorry, I have little sympathy for you. When we were first RV'ing with class C's and then A's, DW had similar issues. Her solution was to sit at the dinette and pull the shade. We drove some side-of-the-mountain western roads with switchbacks, drop-offs and very narrow roads. Az89 from Prescott Valley to Clarkdale and AZ89 from Apache Junction to Tortilla Flat campground with a 40' rig pulling a 22' pickup. Since then she has learned to drive the rig and has driven such roads both in the lower 48 as well as in northern Canada and Alaska. Learn to drive your rig, and get comfortable on easy roads. then when things get more challenging, you drive (with some coaching, at first). Now DW drives, I sleep and visa-versa. And do I get an ear full if I exceed my 2 hours in the seat.
