Looks like the new 7.3 V-8 is not such a powerhouse after all, just a tad more than the V10..And with all the issues the 1st and 2nd years of anything new who wants to be the 1st to try it in a new motorhome that to will have its issues..I will keep my old school 2008 V-10 5 speed, Bounder with the Banks Power Pack system, 5 Star Tuning and pass the new 7.3 V-8 motorhomes on the hills.. https://youtu.be/pg7m5GDNeac

For those that dont want to watch the video here is the specs..7.3 V-8 >> 430 HP at 5500 rpms and 475 lbs of torque at 4000 rpms.. ……………..……………………………………………………………………………………………………………...………………………………..That is higher rpms at max hp and torque than the V-10...2006 to 2017 Stock V-10 output is 362 horsepower at 4,750 revolutions per minute (rpm) and 457 foot-lbs. of torque at 3,250 rpmMy 08 has max torque at 3300 rpms, 500+ lbs of torque with the Banks and 5 Star tuning...

Made for towing, not racing. Flat torque curve, 400ft lbs at 1500rpm

Wow it appears the 7.3 will be detuned to a lower HP and torque for the F-53 motorhome...In fact, the new engine will be available in two power output versions. The less powerful one has 350 hp (261 kW) and 468 lb-ft (635 Nm) of torque and will be standard on F-450 chassis cab, F-550, the new F-600, F-650, and F-750 Medium Duty trucks, as well as the F-53 and F-59 stripped chassis models and the upgraded E-Series. The 450-hp variant, in turn, will be available in the F-250 and F-350 trucks, joining the already offered 6.2-liter V8 and 6.7-liter V8 diesel.Jeez what's the point Ford less HP and almost the same torque as the 3 valve V-10 in the F-53...https://www.motor1.com/news/362862/2020-ford-f-series-engines/

Why? It’s cheaper and utilizes components used on the smaller V8. I’d worry more about the ten speed trans.

That is higher rpms at max hp and torque than the V-10...
