I couldn't find a suitable cargo liner either. I just wanted something to weatherproof the rear of my wrangler, as anytime the carpeting got even slightly wet it smelled awful for days. I ended up buying a 4' x 6' recycled rubber mat from Lowe's for $29 and cutting it to fit the back of the jeep. I used the old carpeting as a template, so I got it to fit perfectly. The top side of the mat is textured with a "diamond plate" type pattern, so flip it over and use a razor knife to cute it on the flat side. The mat reaches all the way under the rear seat, into the rear foot wells. The excess I cut off made nice rear floor mats, so the entire back of the jeep is covered in a single, uniform material that gives it a very professional, finished look. It looks like a custom mat you would pay $100 dollars for. The rubber mat is nice, it is made from recycled tires and is about 1" thick. It provides cushioning, gives the rear of the jeep a rugged but finished look, and you can take it out and hose it off if it gets too dirty. Best of all it doesn't absorb and hold water, so it won't get musty and stink like dirty gym socks!
