I currently have a 2005 Silverado 1500HD 4x4 and I get about 10mpg towing, 11mpg in city, and about 13 mpg highway. I tow a 6x10 open trailer with mower and trimmers about 2 days a week. I'm thinking about trading for a 2008 Toyota Tacoma 4x4. I've looked up the average mpg from consumers and they have been 16 city and 20ish on highway. Looking for opinions.
