Ya a snatch block will be key with a 6000Lb.
As stated above the more wraps on the drum the less the effective pulling power is. I have had to use my snatch block before on my 8000Lb 8274 just do to the fact of how short the pull was and I was stuck good.
The main problem I see with it is the limited use. By having to use the snatch block you cut in half the distance to an objet to pull off. There have been a few instances where I can reach an anchor single line but I need to double line it. Ya I get really stuck some times. Then things get tricky on what to do. And this is with 150’ of cable on the winch. For this matter I carry another 100’ of extra cable. I would guess you have around 100’ to 80’ on yours.
One other thing with a winch is once you have one you try things you wouldn’t have tried before, by yourself at that matter. This can lead to you getting really stuck. And I look back to a few instances of mine and I would have hatted to be where I was with a 6000Lb winch.
It was free so put it on your truck but get a few things to make it a valuable tool on the trail.
Tree strap, snatch block, rigging chain, and some extra cable.
