Every year, Jeep enthusiasts gather in Moab, Utah, for the annual Easter Jeep Safari, and as it has for the past several years, Jeep will debut several one-off concept vehicles at the event. This year's crop is led by the stunning Jeep Chief, a throwback to the Willys-era machines with surfer influences, and the first factory customizations of the new Jeep Renegade. Other models include a tribute to WWII-era Jeeps, a camping-ready variation of the Grand Cherokee and a couple of extreme off-road versions of the Wrangler.
