It's really hard to find good info on exactly what winch ratings mean. For the most part, what I've found is that a 5000lb winch won't lift 5000lb. It means that it will pull a 5000lb rolling vehicle up something like a 20% slope.
Does anyone know of where we can get accurate info on exactly what various winches are capable of doing?
You can't fix stupid...
but you can numb it a bit with a 2x4
