Spends too much time on here
Road tripped from North San Diego to South Lake Tahoe (~520 miles) and amazingly averaged around 16.5mpg (hand calculated since my speedometer isn’t calibrated)! For such a big truck on 37” MTs I’m stoked I got that high. The exact same trip when the truck was bone stock was 19.5 mpg and the exact same trip with 35s was actually about 16mpg so my mpg got BETTER with the 37s somehow!
Did you correct for the odometer error in your hand calculation?
