Charging Trailer Battery
I have an 06 QCSB 6 speed... I tow a 22' gooseneck and it has a 9000lb winch on it with a battery. Instead of taking the battery off to charge it, is there a way to charge it using the tow truck? I have heard of people wiring their trucks and dump trailers to do this so they don't risk having a dead battery when they go to dumping something. How could I go about this? Thanks in advance.

There is a circuit in the 7-blade RV plug for just such a purpose.

TonyB beat me to it with your answer. You can wire the trailers plug to supply the +12 to the battery off the trucks output.
I picked up a small solar panel and connected it to my winch battery on my trailer. It keeps the battery (and the elect brake emergency battery) always fresh and fully charged at all times. Batteries certainly last longer when they are constantly being kept up to par.

Has anyone tried wiring a winch on a trailer directly to the battery/charging system of the truck eliminating the need of a battery on the trailer? Would anyone recommend this?

You could get a male & female set of these and mount on the vehicle so you can't connect the cables wrong. Then get a corresponding set of cable connectors for the trailer, some cable and do it that way. The only drawback is that it'd run your batteries down pretty quickly.

A diode will not work in the application you are thinking about.
However, you should have some kind of relay to isolate the truck 12V feed from the trailer. That WILL keep the trailer from draining the truck battery. The alternative is to just unplug the 12V/tail light plug from the truck, when it is not moving.

As Belgrath04 said... What kind of amps can you pull through the factory plug? Is it enough to possibly keep a battery charged? I do not want to wire my winch to the truck battery if there is a possibility of screwing it up...

The 7-way battery feed has a 30amp fuse so it can't handle more than that. While that's enough to charge the trailer battery it won't be fast about it. Also if your trailer battery is real discharged you'll blow that fuse because it'll draw more amps trying to charge the battery back up.
