towing with a silverado 6 speed
Was wondering if any one tows in 4th gear with 3.73 gears and if so is gas mileage better or worse. This is with a gas engine.

I use T/H mode and M5 most of the time and tow at 67-70mph usually, sometimes faster if its cool. Only you can test if 4th gear is better for your combo and conditions. I expect FE will be unmeasureably different if it is shifting that often or spending more than 25% of miles in 4th anyway.
