30k is well over any F-350's GCVWR. Your "approved" by your DMV. Not the DOT, who usually enforces the Federal regulations.
My Dodge is rated for 23K total combined weight. That is the legal weight as per the manufacture. That is the weight amount that most states go by. You can have 80K plates, that dosen't mean for one second the truck was ever meant to run that heavy or that it is "legal" to do so". Meaning the police can issue a ticket if they want to.
Any owners manual has a very clear towing guide.
At 30K (26,001 actually) you are required by Federal Law to have a CDL with a few exceptions including: Farm trucks driven within 150 miles of the farm, service men in millitary service, RVs or non-commercial activity. The truck still needs to be within the weight limits of the manufacture to be "legal".
With that said, most rual police will not enforce DOT requirements on local farmers. RV's are exempt in most states for some reason. Commercial trailers are limited to 10K, after that you need a Class A CDL. In GA we have a non-commercial Class B and Class A for farmers.
There is very little enforcement for non-commercial trucks though. You probably will never have a problem if the DMV let you have 30K plates. Do you have a CDL?
For those interested in hauling over 26,001 in a non-RV or non-farm truck:
Federal Law:

Class B -- Any single vehicle with a GVWR of 26,001 or more pounds, or any such vehicle towing a vehicle not in excess of 10,000 pounds GVWR.
