Looking to purchase a one ton 4 x 4 Diesel Truck to pull a fifth wheeler. Have not purchased the fifth wheeler yet, so wanted a truck that will pull just about anything. Will probably get a large 40' Toy House. Should I get a Short Bed or Long Bed? Four Door or King Cab? Dually or Single Rear Wheels? I like the way the 03' 7.3L Diesel F350 King Cab Short Bed handles and drives, but don't know how it will handle a large fifth wheel. I also like the room of the 03' 7.3L Diesel F350 four door long bed. Thanks in advance.
