25000 miles towing my 7500# trailer I have averaged 9.3 MPG. Same 3.55"s and hemi. No problems pulling the highest passes- I live in Colorado. Hook a diesel on this trailer and it would do 12 MPG. The diesel option is $7800.00 so I can buy a lot of additional fuel for the additional milage of a diesel.
