back where the plastic is that covers up the spare tire. anyone ever get annoyed that the carpet follows the curve of the floor and leaves a big gap between the floor and the pannel? maybe it was only on mine i dunno but cut a 7 inch wide and 2-3 foot long very skinny peice of wood and lay it under the carpet. the wood has to be off center to the spare tire side though because the other pannel wont fit right but anyway it works and there will be no more gap.
