5.7 with 3.21 Rear Axle in 2021 Limited Gas Mileage ?

[CogitoErgoLevo]

for 30k miles or so I was getting about 19mpg. 40% city/60% highway.
But I moved and now I get about 13mpg 100% city. I encounter about 15 stoplights in 5 miles and barely get to 40 mph.
If I didn't have e-torque, I bet I would be getting around 10mpg.

I tow a 5200lb travel trailer with the truck loaded with kayaks, bikes & camping 'stuff' for a 2 week trip. I avg 12 mpg towing, 16/17 mpg around town & 17/19 mpg highway... See signature for truck details... And to quote others, I have a 'green' engine, it only has 6000 miles on it...
