My better half had never driven our dually except for a five minute test drive when we purchased it. Had never even thought of pulling the 5th wheel. Coming home from Charleston, SC last year, I'd had trouble with double vision. According to her, I was all over the road, since I didn't know which two of the four lanes I was seeing were the true ones. We got into road construction shortly out of Charleston and had to stop, so she jumped out of the truck, came around to the driver side and demanded I let her drive. Good sense prevailed and I reluctantly got out. Unfortunately, we'd just had DVD players installed in the rear of the front seats for the grandkids and since I'd never needed to adjust the seats and mirrors for myself after setting them up in memory, they had been disconnected during the installation. Neither the seat adjustment nor the mirror adjustments worked, so she sat on a pillow and leaned back on her purse and we took off. I woke up going up the road and she was trucking along at 70 mph. She drove us the next 400 miles to home, avoiding having to back up or do anything exotic. By the time we arrived home, I was able to see well enough to back the RV up and park it. Needless to say, my wife now knows she can drive the dually or pull the 5th wheel when necessary and I would be very comfortable with her doing it anytime now.
