Hi centered is the key phrase SKB. That is why I remove the spare on my Landcruisers for winter driving. That is where they can get hung up in deep snow, converting your vehicle instantly into two-wheel drive. At least its easier to shovel out the rear instead of the center.
The spare tire winch on my '85 was so rusted out from neglect or lack of use that I had to have it cut out with a torch to drop the spare. Don't know what to replace that winch with as they are not available. Any suggestions appreciated!
