tallmandan Posted June 16, 2022 Share Posted June 16, 2022 With towing MPG certainly a bigger consideration these days, I thought I would share the fuel economy numbers from my last two trips up into the Colorado mountains and back while towing my LEII. (Water tank full outbound and empty on return) This is a stock 2021 Silverado 1500 with the 3.0L diesel in-line 6 cylinder. If you are considering a new tow vehicle, this truck has been solid and comfortable. Power and control towing both up and down the mountain passes in Colorado. The only shortcoming is limited payload in the truck and use of WD hitch, as has been discussed here for all half ton trucks - but these haven’t been a problem for me so far. Almost 17k miles and zero problems. 9 1 2020 Elite II #627, 2021 Silverado 1500 3.0L Duramax, Colorado Link to comment Share on other sites More sharing options...
