Too many miles?

We drive those kind of miles on long trips. My husband could drive from sun up to sun down. We packed a lunch, at each gas stop we each used the camper bathroom and I walked the dogs. At night, we would pull into the campground, did not unhook the camper, put down the stabilizers, plugged in the electric and hooked up the water. I would already know what I was making for dinner - I preplanned all that for the days on the road so we had meals that usually had to just heat up. After dinner, my husband chilled outside while I exercised the dogs and took a shower. Got up at 6 a.m. and started out again. It's not fun - but doable.
