i have this 12,000 pound line in my mind for vehicle recovery. if your just hauling logs for fire wood, and pulling out friends on an icy morning...8,000 seems ok at best. shackels and pullies will double your abilities, but then there is the set up. I might be tempted if there was not serioous off road 4x4 being done. have fun choosing. i am going down that road myself as well.
That looks like a pretty good price and 8000 lb is plenty big for an FJ40. I forget the formula that's a rule of thumb for sizing a winch in relation to the vehicle weight but I've checked it before and 8000 is fine. As was said, you can use a pulley block to double the pull. A couple of years ago 4 Wheel Wholesalers had this winch for right around $500 or a little less and I should have bought one. I checked the other day and the prices are way up on WARN. You might check Clemson Off-Road, they usually have good prives on WARN and usually free shipping.
