Hello, went camping up to Bass Lake with our 1 year old last summer (went again this summer, it's an annual thing, she was 2 this time). It is a 5 hour drive for us, and I knew her limit was like 2 hours in the car awake, so I planned it that we left at about 6:30 pm, stopped for dinner at 8, changed her into PJs and she conked out for the night after that. Of course, that meant arriving at midnight and setting up our tent by flashlight. Not the best, but it worked for us and we were camping with a ton of other people who were already at the site and had a spot staked out for us and were happy to help us (we can be a rowdy group, yes there were still some up to greet us when we arrived at midnite!)
This nighttime driving plan worked better on the way home because no tent to set up back at home. We just didn't unpack the car till the next morning.
As far as camping she did fine, we did not adhere to a nap schedule, it happened when it happened. I never know what time it is while camping anyway. At night she was in her packNplay in the tent, covered with tons of blankets (it will be cold no matter where you are camping!) During the day she usually slept on a pile of beach towels or a raft in the shade (it is lake/beach camping there).
I did bring some brand new toys for her to entertain her on the ride, and when we were in dire straights at camp. Mostly she did not need toys or diversions while camping. The people, the water, and nature were enough for her. But it did help in the car.
Wore almost every outfit and pair of socks we brought... they get dirty!
Don't know how long or where you are going, but we gave her a little rinse in a sunshower every day in the late afternoon, I liked thinking she was a little clean...
Have fun! It won't be too difficult, just go with the flow and you'll be fine!
