30 day trip out West - Dare we without reservations?

One big reason for a truck camper.....don't need a reservation

Bingo! I agree.

However, while we were in Yellowstone a few years ago, I made a reservation at a different campground inside the park each night. Good thing I had reservations because all the campgrounds were booked up (July). Yellowstone is huge and since you can only camp in Campgrounds while in the park, having reservations was critical to ensure we didn't have to waste time backtracking outside the park.
