I am thinking hard the next go around getting a truck with diesel power or a gas truck that is a 3/4 ton. I am pulling trailers all the time for pleasure and work during the summer and I feel like my Toyota Tundra is getting very very poor fuel economy pulling a trailer. Example: pulled my tractor to the farm to do some work, averaged 9.8 MPG pulling it up and back 100 mile round trip and my rear end of my truck was to the ground even with the weight of the tractor on the axles. I could get air bags but it wont solve the entire problem. Average fuel economy running around town is 13.4 MPG, and highway is right at 16 MPG. The toyota tundra 5.7L motor is the strongest, most responsive motor around in my opinion, if it was not for the fact that I need a 3/4 ton truck for pulling heavier loads, I would definitely keep it or if toyota would wake up and put a 3/4 frame and rear end in the trucks! . I will probably cry when I get rid of it but I am shooting myself in the foot.
Question is this...What does the bigger trucks get for fuel economy pulling trailers, daily driving etc. I have heard rumors that some of the 3/4 ton trucks are getting 20 MPG on the highway...who knows if thats true...your thoughs please. Thanks
