Thanks so much to all of you guys that provided me with ideas for how to eliminate this smell. I found that spraying my whole interior down with a strong mix of vinegar and water followed by a sprinkling of baking soda on all the upholstery followed yet again by another spraying of vinegar has almost eliminated the smell. After scrubbing in that solution of vinegar and baking soda into the seats and carpet and headboard lining with a soft bristle brush I then let it sit for a few hours. I then vacuumed it all up with a good ShopVac and hosed it all down with Febreeze several times. I also replaced the cabin air filter. I believe there is still the faintest smell still left, but it is pretty well over powered by the febreeze.
