Good one FJ. laugh

I did the same thing once. I took a small cooler with 2 dozen sandshrimp in to work with me, I planned on fishing after work that day. There was a train derailment and I had to leave town for 5 days. I had left the cooler in the cab of my truck. It was in july when I did this. The smell was so bad you could small it even before you opened the door.

I used Frebreeze on all of the interior and it worked pretty good to get the smell out. If that doesnt work take your car to a detailer and have them steam clean the interior.
