Thank you all for the comments they are helpful, as it gets closer we will have to decide how we are going to plan our stays. My wife and I are not the typical tourist, we are there more for the nature site seeing. We tend to shy away from tourist spots, but we do like things like Indian ruins, and cliff dwellings and such. But that is the nice thing about not having a schedule, we can drive around, or stop and see what ever takes our fancy the time. We would not have a problem staying at a rest area, except for the security issue when you leave your rig. The plan is to use the trailer for sleeping, the rest of the time we plan to be out and about. We are pretty good fly by the seat of your pants people, so I think it will work out fine.
