We spent a week in Moab in September 2018, and we rented a Jeep from John. The Jeep was Amazing! We put it through a lot and it just asked for more.
From Hell’s Revenge to Wipeout Hill, it didn’t miss a beat. John is a great guy and will give you great advice on Moab, which trails are most suited for your level of experience. When we go back we will be renting from John @ Jenn’s Jeep Rentals again!
