man you will need cdl class a towing over 10,000 lbs check your state you will fall under fed law across state line
Only if you are towing commercially (i.e., you are being paid to do it). If you tow for personal (non-commercial) purposes, all you need is the appropriate endorsement for your DL.
When I haul my antique Caterpillars to California for antique tractor shows, my Class "F" endorsement (loaded trailers over 10K pounds) is sufficient, as long as the equipment is all mine and I'm not being paid to haul anything for anyone else. Also, the GCW must not exceed the vehicle's manufacturer stated GCW.
But most 3/4-ton and 1-ton pickups nowadays are rated to safely tow well over 10K pounds, and newer 1/2-ton pickups are being uprated to tow nearly 10K pounds.
For the OP, if you've never hauled heavy loads with pickups before, I'd say don't do it...follow the other posters' advice and rent an F-450 with dual rears to tow that gooseneck trailer. What is the trailer rated to haul? Have you checked its brakes? For loads that heavy, you better have brakes on every trailer axle (some older trailers only have brakes on one axle). Do you have proper chains and ratchet binders to secure your load? That is just as important, for if the load shifts or bounces, it could induce sway and instability, as well as the top-heaviness making it even more unpredictable...you've got to be able to solidly tie down that Deuce so the springs don't rebound after going over a bump in the road. Good thing you're not driving in California, those freeways and roads are so rough and torn up that your truck & trailer will be constantly bouncing most of the way.
And if you're not sure, then place the front of the Deuce first on the trailer, closest to your towing rig. Only place the engine rearward on your trailer if you thoroughly know your trailer & towing rig, and have experience doing so.
