Hello -

I own a 2013 2500 with 5.7L gasser.

I am contemplating getting a 1500 of same year-ish with same motor.

Question is: would the 1500 get better fuel mileage than the 2500?

I understand it depends on the rear end ratio, bed/cab size, etc. My question is theoretical. Same engine in different chassis. The 1500 being lighter would get better mileage than the heavier 2500. Right?

In theory with the same motor a half ton should get better gas mileage then a 3/4 ton. There are a lot of variables that come into play with gas mileage so how much better is anyone's guess.

I've never had a half ton with the 8 speed but from reading on here I think a lot of people would recommend it over the rfe if you do go the half ton route.
