Looking at buying a winch for my car hauler. It's a 7000 lb 16' double axle trailer with ramps (no beaver tail).

What size do you guys use? 6000 lb? I would have it do double duty and be able to use it on my truck in case I ever got stuck. It's an 05 Ram QCSB 4x4, probably around 5500 lbs with me in it. I don't off road at all, but I do use it as a truck, so the worst it would ever have to pull me out of would be snow or some mild mud (more than likely snow, snow was my nemesis this winter)
