Anyone bought one? I would like to protect the back, I put stuff in and out alot and don't want to trash the interior. Anyone seen a good cargo liner?

 

If you Google "Chrysler Aspen" you will find several companies with accessories. There are two or three different rear liners available for the Aspen. I would give you the referrals but I am out of town and don't have records with me.
Let me know if you don't find what you are looking for and I will give you company names when I get back to the home base.
