Truck rear-end gear ratio vs. mileage. So, which "rear-end" offers better mileage; when towing an 10,000 pound trailer; and 3.55 or an 4.33 rear-end?
Would the overall affect be the same for Diesel and Gas?
Looking at an Ford F350 and at the moment don't know which gear-ratio woujld be best. I know Diesel engine is better but at an $7000.00 premium over an Gas engine - that $7000.00 can buy a lot of fuel.

Thanks
