F53 Horsepower rating

Also many times a manufacture will request a lower HP engine, for their entry to mid entry RV's. Saving the higher HP for their higher end RV's. (Much more so in the DP side of things...). The F53 comes in different weights, as well as different levels of suspension components. Look at some of the entry Class A's on the F53 on shorter wheel bases... Easy to spot with the large 'Tail wagging the dawg.' overhang:)!. Some Entry level coaches with the F52 will not have rear pan hard bars, and or smaller, or even no, sway bars. It's all about marketing, and hitting price points.

Can't say if the lower HP is part of this or not, as I was not even aware that the V10 came in different HP levels within the same engine year:)!

Not sure where to start.

1. Ford does not offer the F53 chassis with different V10 rated engines to the house builders. All, within a model year, have the same power specifications.
2. Regardless of wheel base or weight capacity Ford supplies ALL F53's with the same rear overhang length, 105.8". The house builder will add extensions of various lengths as needed for house design. The perceived value of the coach has no relation to overhang. Easy enough to compare a Thor Ace 27.2 to a Fleetwood Bounder 36H to a Tiffin 36UA with regard to rear overhang and it is pretty apparent the Ace has the smallest overhang ratio, smallest wheelbase and the lowest price.
3. Since 1999 Ford has NEVER supplied a rear trac or pan head bar on the F53 chassis and ALL have been supplied with front AND rear sway bars.
4. There are no engine model years only chassis and not every calendar year has a new chassis.
5. Since Ford has never published a torque or a horsepower curve for the V10 engine comparing the different published performance capabilities is difficult.

The latest numbers are the fourth revision since 1999 when the V10 showed up in the F53. Why the change? Who knows. CAFE standards, EPA, lower top gear ratio of six speed transmission along with the rev limiter settings, and the list goes on.

Regardless, the chassis will get the house built on it and all its occupants anywhere in North America on improved roads as long as it is operated within the limits Ford provides. You want to take a logging trail or fire road to "The Spot", you're on your own.
