Hmm, having difficulties finding you a driver at the Grand Canyon.
I've never had success with a ride service outside of a city, and outside of cities is where RV sites that people are interested in tend to be located.
It's crazy how different people's experiences can be, while seemingly performing the same activity.
We fulltimed in western US, and I made it a point to minimize RV parks & paid camping, to see get more out into nature. I honestly don't even know what it would be like to just go from RV park to RV park.
