With the growth of RV tourism, campgrounds across the country are struggling to keep up with demand, resulting in campsites being booked months in advance. Campground reservations in Yellowstone and Yosemite have increased by 50 percent. This shortage has forced some travelers to visit remote areas on public lands or less regulated areas. In addition, private campgrounds are expanding, and a new camping app is helping RVers find available space. Experts believe that as more people opt for road trips instead of air travel, the demand for RV camping will continue to increase.
