For comparison sake I have a 14 Screw, 3.5 Ecoboost XLT 6.5 bed. Xlt comes in many configurations. Mine has power driver seat, power pedals, chrome package, chrome steps, 20 inch tires, tailgate step, backup camera, rear power slider window and linex spray in bedliner. Also Max Tow with power tow mirrors and 3.73 E-Locker rear. Gvwr is 7700#. Payload is 1735#. Buyout at 36 month lease end is 26K. Tow a 7700# TT with a tongue weight of 835#. Tows like a baby diesel due to torque at low rpm and the adaptive learning transmission has learned my towing methods and downshifts before I do. Got this truck because DW had 2 spinal surgeries and was in line for a 3rd and this truck is very comfortable. Had an older GMC 2500 with 6.0 and 4.10 gears and the Eco is far superior in all categories. Hope this helps. Good luck.
