Increase your Ram's Payload by 50%

I had a Hemi in a Dodge Aspen It got best of 12MPG unloaded. With a load it probably would get 7-8 MPG. There is NO WAY that truck gets 16MPG with a Hemi in it. That thing is a Gas Pig.

I have a 6.0 Diesel Excursion that has 750ft lbs of torque that will pull anything like its not even there. It gets 22MPG pulling a 10000lb boat and trailer all day long. 70MPH up 6% Grades at 1900RPM towing like its on Vacation.

Try that with a Gas Engine. It will not happen.
