An FYI as well as wondering if other owners are having the same problem.

I bought a new F350 V10 in 2010. It has leaked oil almost from day one. I've had it in the shop 4 times for this problem. The oil has leaked around the oil pan and several attempts to stop it have failed. Turns out that the gasket flange has ripples in it. The shop brought in two new pans and they both had these ripples. They finally took a pan off a new truck and found it to be smooth. I've had my truck in the shop for at least 13 days over this issue. That equates to 13 days of lost work.

If you've had this problem and the fix was gasket sealer, you might want to insist on a more permanent fix as mine kept leaking in time. You can see the ripples on the right half of the pan.
