Hi all I know there are some threads out there about this but none I found were specific enough so sorry to open another! Just bought my first ram. Always been a Ford guy! I like my 14 2500 5.7 4x4 crew cab long bed quite a bit so far. This truck has 3.73 gears and it does have 285 tires on it. I know we don't buy these trucks for fuel economy but I just took a rd trip about 200 miles and the truck seems to be getting under 11 mpg. I do not have a heavy foot I did have the cruise set to 75 most of the trip the tach was sitting about 2500 rpm. If this is what it gets so be it but just seems to me awful low for even this truck. So, looking for any advice on what I can do. I worried what it will get with 10000# behind it!! Thanks in advance.
