Hard to find info. I just bought a 2017 XLT crewcab with a 3.5L non-eco boost. It is rated to tow 5000#. I am towing my 2500# Triton Aluminum. It tows the Triton very nice in the city and on the highway. Enjoying the truck. Getting a consistent 14.5 mpg towing. It’s not easy finding real world info on the motor and rear end set up, so thought I’d report, how this base model tows/performs. I drive about 12,000 a year and tow about 500 miles a year. Remember I am in Flat land Florida, so limited hills. I’d love to hear what any one else is towing and their story about this set up.
