Well it seems for all the the reports diesel still has better mileage and by a good bit. The intresting part is comments like it does ok or I am fine with it for gassers. I tow 11,000# with my 01 Cummins. It has a small chip maybe 260 to 270hp, with 3.55's I am technicaly about 3,500# over my GCVW at 19,500#, but have no issues in hills or flat. All that an 12 to 13 mpg towing and 20 mpg highway 14 to 15 mpg city. Yes I am impressed how well a 14 year old 270,000 mile diesel runs and pulls!
Throw in a set of stock Bosch 275 RV injectors. Your mileage will improve and performance.
Sitting on the shelf in the garage, just waiting for the right spring day to get installed.
Same thing when you have a 12V with an auto, stick in a set of Bosch stock 215 injectors. I did with my 12V and increased mileage by 1 mpg+.
