2011 Pro 4X little cab here. Got it brand new and it has about 16,000 miles on it. Driving around my small town I see about 18mpg, driving in San Diego traffic I saw closer to 16mpg. Loaded down with Two guys, all their gear and two dirt bike I got 19mpg between here and Moab. My trip from here to Cabo saw me with an average of mid 18's mpg wise and that included that San Diego driving. I love it, but do feel like some others have mention that it gives up a little in fit and finish to my 2001 Toyota Tundra, but that thing reeeeally had shit mileage with about the same power. The seats do stain easily but as a "dirty" person and dog owner who really cares it's a truck. Overall I'm happy with my experience so far.
The utilitrac is awesome for up to three bikes. or two and a weekends gear.
