Our Story
Diff. is locally owned and operated. We provide 4×4 rentals in Southwest Colorado throughout the year. At Diff Auto Rental, we want every experience to be exceptional. We love the San Juan Mountains and want to promote responsible outdoor recreation! A portion of all sales are donated to Tread Lightly to maintain public lands. Colorado Highway 145 is a 115-mile scenic road that passes through Colorado’s largest mountain range. The road sign provides direction through the mountains for both residents and visitors. For us, the sign became more than an image of a highway number and the Colorado flag. It became a symbol. Small towns. Great People. Outdoor Adventure. Diff. is a lifestyle built around the mountains!
