2015 Ford F-450 Powerstroke. Has anyone ordered one??

I have a 08 F450 6.4, thinking of going to a 15 F350 towing a 38' Mobile Suites, reasons; better fuel mileage because the 450 has 4:30 gears only, F350 has 3:55, 3:73, 4:30 depending on what you plan on towing. F350 Lower insurance cost, lower registration fees (CA) F350 better daily driver than 450 (sightseeing without trailer),tire mileage on 19.5s is not that much better than regular E rated tires in comparison to cost. Handling Comparison? use your saving to upgrade the brakes on trailer to disc. JMO as a current 450 owner.
Note in tow guide that tow rating are controlled by max hitch capacity
