I drive the DW navigates. When I get tried, I nap and she drives.
She leaves the winding through city streets to me while she navigates but any normal road; Interstate, US highway or County is fair game for her.
Since I do not like to ride and she likes to knit, tat lace, crochet or quilt while I drive; I drive about 90 percent of the time.
Backing in to a campsite is easy, she stands to the side so I can see her in the mirror and guides me in so I do not hit anything. My iron clad guarantee states, "I can park the TT within the first 12 of 15 tries." No excuses. :)
I discovered very early on, that those few time I backed in perfectly on the first try, no one reduced my camping fees or ran out and presented me a medal nor did it show up on my permanent record from high school. :) :) After that it became less of an issue.
