The SLE is our choice for those looking for a comfortable working truck that doesn't break the bank and is easy enough to live with daily over long distances. As with the Pro, the features list is a tad short, but the SLE adds some important comfort features such as cruise control, the multi-function MultiPro tailgate with EZ Lift, and power door locks that make the daily grind that much easier. Standard features on the SLE include a 12.3-inch color driver information center, a 13.4-inch infotainment display, a compass, steering-wheel-mounted controls, power windows with driver express-up/down, and cloth upholstery.
