I don't know how much this applies to prepping, but I thought I'd share a real world lesson I learned this week. I recently got a tilt trailer to haul a scissor lift that we got for the business. The lift has a hard time driving up the steep incline on the trailer so I bought a 3500lb winch to load it on and off. The lift weighs 2400 lbs, so I figured that's well below the winches rating. On the third or fourth time we used it the winch toasted. Piece of junk, called traveler and from tractor supply. Anyways I returned it and got an 8000lb winch this time. The problem is it's got a much larger footprint, so I had to fabricate a heavy duty bracket on the front of the trailer for it. Hopefully this one will last a while, but I bought the warranty just in case. So, the moral here is if you're thinking of getting a winch for a vehicle, don't believe the rating on it! The down side of the new one is its about 100 lbs. and it's a lot bigger and heavier than the first one, and of course more expensive.
