I currently tow approximately 8500 lbs with a Tundra. The Tundra has 5.7L V8 381 hp/401 lb-ft with a 4.300 rear diff. Looking at purchasing a Ford F-250 gas 4X2 with a 3.73 rear locking axle. Will I get a better ride with the F250? The Tundra is rated to tow 10,000 lbs and I had to add air bags to the rear end. The Ford is rated to tow 12,000 lbs. Will the 3.73 rear locking axle be an issue? Would it be beneficial to upgrade to the F-250? I appreciate your thoughts and opinions.
