It all depends on your DW.
My wife has driven a few times when we were "out west" on the open highway
in light traffic. IF I can get a short cat nap of just 15-30 minutes it REALLY
can help my comfort level- especially on those long haul days.
She doesn't like to drive it. She is NOT having any fun when she is driving.
I want her to have fun on our trips so I drive 95%. Not a biggie.
What she does do WONDERFULLY is back our rig!
I walk along side and talk to her..... I say things like back easy, now left
a little, center your wheel, now right a little, a little more right. etc etc.
She is like the perfect remote control. I walk around, look for obstructions
get out the leveling blocks and SHE parks that baby just where I/we want it.
It's probably the ONLY time she does EXACTLY WHAT I TELL HER TO DO
She also backs the truck when we're hitching up. I can get the TT on
the ball 1st time every time with her driving and me giving directions.
We tried it with me backing and her giving directions but that just didn't
work for us. She'd say things like "get over" or "not too close"
or "watch out!"
I had no idea what she wanted me to do and we actually had a fight once
or twice early in our travels. Who wants to arrive at the perfect camping
spot and be mad at each other??
Once we discovered she could do it if I gave
directions MY blood pressure went WAY down on arrival at a new CG.
It works for US. Why not give it a try!
