I currently have a class c motor home. We want to change to a Fifth wheel toy hauler. To do this, I obviously need a truck to pull it. I have an F150 pickup now that I plan to trade for an F350. I know that the diesel has more power and is supposed to give better mileage. However, I have been advised that the diesel is not good for running errands, short trips to the lumber yd. etc. Primarily, the truck would be used for that purpose until winter when we head south. The other option is a V10 6.8L engine. I know it will pull the 5th wheel. That engine is in my class c. They also put them in class As. Any advise on which way to go.
