We did a road trip like this in 2009. We started with the idea of renting a small camper, but -- after looking at prices -- we figured out it was cheaper to stay in hotel rooms.
Much cheaper, actually. I'm using 2009 prices: the camper rental was going to be almost $1000, and they charged a per-mile cost on top of that. And we realized just how much gas those campers require. In the event, we were glad not to be driving a big clunky vehicle through some of the cities we visited. The math might've been different if we knew someone from whom we could've borrowed a camper.
What we did:
- We had planned to do a month, but my husband's job forced us to reduce it to three weeks. As a result, we flew to Vegas and rented a car and drove among the Western national parks (we are on the East coast).
- My husband was traveling for work a good bit then, so he purposefully chose specific hotels to build up rewards points. About half our hotels were free or reduced because of this -- we saved points for about two years. We also stayed in cabins in national parks, and we got some very cheap rooms from Pinterest.
- Our first stop in Vegas was Walmart, where we bought a cooler and filled it with sandwich materials, fruit and drinks. We typically had breakfast at the hotel, lunch from the cooler and dinner at a restaurant. We abandoned the cooler at the end of our trip /left it in our rental car -- but it saved us quite a bit.
- Here's a website that was useful:

- We bought an America the Beautiful Pass at our first national park. It cost about $100 and was absolutely the best value along the trip. Don't buy your pass until your first stop -- your 12 months start counting when you buy it /not upon your first use.
- We spent a huge amount of time mapping out our stops so that our drive was efficient, but we were on the road a lot. At times it was necessary to do a marathon driving-day, but we never did two of those in a row. When we knew we'd be in the car a long time, we tried to plan for a suite or two rooms so we could spread out a bit -- and we tried to get hotels with pools /exercise rooms. We needed some movement after being in the car a long time.
- We visited lots of national parks and historical sites, but we had teens then, so we included a rock concert, a water park and other things that were more "for them" than for us.
- We didn't do everything we wanted; for example, I am still genuinely distressed that I've never seen a redwood tree. We mapped out the major things we wanted to do, then added in things that were "on the way".
- I had a huge notebook with maps, pre-paid tickets, etc. We literally never took a wrong turn on that whole trip.
- We packed light -- one rolling carry-on each /5 outfits total. We washed clothes every couple days. We packed a pair of jeans but no jackets (we traveled in July). This was a mistake, as I was forced to buy $$$ sweatshirts when the temperature dropped to the low 50s in Yellowstone. On the positive side, they were good quality, and we still have them.
- Our favorite stops were the Grand Canyon (North Rim), Mesa Verde National Park, downtown Denver, and Custer State Park.
