We have a 2004 V70 and we carry a lot of cleaning supplies and liquids. Someone has told us they have seen a rubber/plastic liner for the cargo area, something like a pick-up bed liner but the sides are not as high. Does anybody have any product sources? Volvo of Las Vegas says Volvo only offers a flat rubber mat. Also looking for a good car cover as we park under trees with nests. Thanks in advance, AL
