2WD vs 4WD tow vehicle

DW and I are considering purchasing a fifth wheel and a tow vehicle.
The trailer would be in the 30-33 ft range. The theoretical tow vehicle would be a fairly new (less than four model years old) F-350, diesel, crew cab, short box, single rear wheel.
My question is;
is there any advantage to towing with a 2 wheel drive truck, as opposed to towing with a 4 wheel drive truck?
We would most likely use the rig as a way to escape the summer heat here in AZ, and would most likely travel and see more of this great country. For the past several summers, we have driven between 7,000 and 10,000 miles each summer, sightseeing in the family sedan.
Thanks for your consideration.

No difference in towing. But if you go back on muddy roads or go up to the RIM country and it rains. The ground is clay and when it gets wet... well plan to stay longer if you only have a 2wd. Also we do our boon-docking on the RIM and go back on the 4wd trails to camp, I could only go back there with 4WD.

If you don't plan on going off pavement or in snowy travels go with 2wd if you do plan on doing any of those get a 4wd. It's insurance, you don't need until you need it real bad.
