If you are thinking of a F450 is it for towing an RV? I believe the F350 dually is much bettered suited for large RV use than a F450 is.

Why??

Buying a truck that is designed to tow much more weight than what you ever intend on hauling has one major draw back and that is it will not have the right rear axle ratio for towing your load. The transmission is most efficient in 4th gear where it is closest to putting the power straight through. A f450 running at 2800 rpm in 4th gear is capable of putting over 4000 lb ft of torque to the rear axle in 4th gear at 2800 engine rpm which equates to 53 mph. So if your hauling a very heavy load the truck is designed to put full power to the pavement at 53 mph. The f350 would put that same power to the rear axle in 4th gear at 61 mph (about 3500 lb ft of torque). When cruising the F350 would run in 6th gear at a lower rpm than the f450 and save you on fuel and running quieter. If you don't need the capability of the 450 you would be happier with the 350 dually.
