Get double batteries ...

If you're spec'ing a dump trailer, be sure to spring extra for double batteries. It's money well spent. I've been transporting and dumping 50+ tons a day, and my hydraulic dump has not slowed down one bit. The fact that my pickup is newer might help, with thicker wiring back to the 12v in the socket.

Previous to buying a dump, I rented them. Single batteries, even brand new, start to slow down seriously after 4 dumps. I ran a 110v cord from inside the cab back to the trailer's charger. That helped some.

The newer Super Duty trucks don't put out many amps to the 7-pin connector. You might see 15 to 20 amps.

Not surprising, Furd is cheaping out more and more these days.

What would a gen1 SD see in amps back there? I have an 04 but don't tow heavy with it. The 6.0 isn't up to the task.

I have an E99 F550 4x4 200' wb that I'm building out to be my primary tow rig for quarry trips. I plan to wire its trailer plug with 10 gauge.

I can't help with the amps for an older truck.

Running a dedicated wire of sufficient gauge is the way to go. 10 gauge wire is not stout enough. A DC-DC charger may be necessary to limit the number of amps that get pushed to the trailer.

Well it was a elec/hydr boom truck in its former life, and I saved all that cable when I removed the bed. Maybe I'll wire it up with 00 gauge back there, lol.

Yeah, the amount of uses is limited only by imagination and the OE alternator jamming through 2 AWG.
