So I was thinking about other than how to mount it what accessories I need. I was wondering if I could build a self recovery device with a disk blade. I what slings and shackles but do I need a snatch block for a 12000 winch?

I was forced into it. I was told I wouldn't be "cool" anymore.

Because I have a snatch block, I use it every time I can. It just makes sense. Also, a second battery is better than a bigger alt.
I run a warn 12k, dual diehard platinums, and 100 amp factory alt. Though I haven't noticed a problem, I plan to add several lights to the rig. Looking at a 200 amp or more soon
