Jim Horne

Senior Trail Guide

Bio

Jim’s passion for off-roading began in the 70s when he would watch his father and uncles race Jeeps, and he took that passion and turned it into a career that has led him to his current position as a core team member of Jeep Jamboree USA. He began his early career in the Air Force as a hydraulic specialist on C-5 aircraft, which helped fuel his love for travel in addition to off-roading. After his stint in the Air Force, Jim and his wife moved to Moab, Utah and opened Outlaw Jeep Tours in one of the most famous off-road destinations in the world. Averaging close to 240 trail days every year, Jim guided every trail in Moab from the easiest to most difficult with everything from stock Jeeps to buggies and racecars.

In addition to guiding trails and gathering the experience in off-roading, Jim also competed in World Extreme Rock series, raced Dirt Riot, the Ultra4 Western series, and King of the Hammers. His expertise and name in the industry led to work over the years with television channels such as Discovery, History and TLC, as well as multiple episodes of Top Gear. As a major testing ground for vehicles and product, Moab naturally led Jim to associations with some of the top off-road companies in the business, including Jeep Jamboree USA. Beginning in 2009 Jim began working with JJUSA by renting Jeeps and guiding corporate events, and eventually began working with JJUSA full time years later. In his role with JJUSA Jim has become a cornerstone in the team which led to him going to New Zealand to build one the most significant launch programs – the media introduction of the 2018 Jeep Wrangler (JL).
