The Ford f350 and f450 pickup trucks have similarities and differences. They are both popular RV towing trucks.
The f450 costs more by about $13k, has larger brakes and tires. It also has a better turning radius due to wider front. The 450 has larger axle and body. It has a larger fuel tank. The 450 is harder to find at dealers.
If you are towing a 5th wheel then having more braking power is useful.
They have the same engines and are close in towing capacity.
