Which truck gets best fuel mileage?

2017 RAM 1500 - 24 MPG. 2017 Honda Ridgeline - 22 MPG. 2017 Ford F-150 - 22 MPG. 2017 Toyota Tacoma - 21 MPG.

The eco-boost Fords and the light duty diesel Dodge are very good. The Tacoma is of course a mid-sized pickup.

Didn't really specify if you were interested in midsize or fullsize, the best in 2017 was the Ram 1500.

The Dodge diesel is expensive so do the math as to cost savings if any (which I doubt). You also have the maintenance costs of a diesel and that blue fluid to add as well.

Rarely ever get question on the Fords but the Dodge 1500 gets hit after hit on whats wrong with My Dodge questions, So parts and Labour on the Dodge in the long run will be more if the last 20+++ years is any indication, So far have not had any I know of on the eccoBoost but we will see.
