We had an excellent experience in Josh’s camper. Both Josh and RV easy were a pleasure to deal with and kept in Prompt communication. Both Josh and RV easy were a pleasure to deal with. The camper was delivered as promised and picked up on time. The camper was as advertised with all the creature comforts of home. We will definitely be looking for Josh’s trailer through RVezy for the Labor Day camping trip next year. 10 out of 10!

The park is located in Lee County, Illinois, near the village of Ohio, roughly a two-hour drive west of Chicago via I-88 and about one hour east of the Quad Cities via I-80. Access is primarily on paved rural county highways off Illinois Route 26, which are generally RV-friendly with no major tunnels, passes, or weight restrictions, though some gravel interior roads may be tight for large rigs. Nearest major airports for fly-and-rent trips include Chicago O'Hare, Chicago Midway, and Quad City International in Moline.
