When you get tired of replacing fuses install a small wattage light bulb in place of fuse. Bulb will glow bright while short exists.
Is the parking light bulb on the trunk lid rather then on the quarter panel? If so I'd check the harness that runs along the left side of the trunk lid hinge. This bundle gets a lot of exercise with opening and closing of truck, and these wires have been known to fail.
