Yes I am aware that there are several F series chassis. However the only one used for the class A motorhomes is the F53. There is also an F59 stripped chassis that's used for delivery vans.
The original V10's were installed in the F series trucks in the mid 1990's. They only produced 265 hp. There have been over a dozen versions of the V 10 introduced since it's inception. They're used in everything from the E and F series trucks to stationary power plants.
Since this is a Class A motorhome forum we only mentioned the ones used in the F53 class A motorhome chassis.
