My diesel, 2003 GMC D/A combo, got four mpg better towing than did my old Vortex 454 which is no longer manufactured. The 454 got about 8 mpg towing my FW and boats while the diesel got around 12.

The gas engine will probably pull your load, but don't look to get the same mph as a diesel, especially pulling a load.
