Has anyone completely covered the rear interior?

i can from a taco but LOVE my ProRunner.
My biggest issue is I'm super concerned I'm gonna stink up and tear up the trunk and rear area. I haul a big stupid dog around occasionally and run a gold dredge as a hobby. Basically I will fold the seats down and carry all sorts of dirty stuff.
I was wondering if there was any ideas to keep the entire back seat/trunk area clean and dry? Weathertech stuff won't work as it's mostly the very rear. I was thinking of laying down a blue painting tarp when I need to load dirty crap in but thought maybe others might have some good ideas?
Thanks in advance!

 

I don't know anything about this product, but it looks like it'll meet your needs better than a painting tarp.

Looks good but I need something that covers the whole back area when the seats are folded down. Thanks though!

 

Here's an alternative solution

 

i was unaware dogs could look that stupid. Rofl. Poor thing.

 

I have been wondering the same thing. I dont have a dog, but haul lots of nasty things when i hunt, work, or just daily life. I have the seats down a lot and need something to cover the whole thing when the seats are down and up.

Thanks, this is perfect and exactly what i am looking for, my cargo area right now is awful looking, wish the new tacos did not suck, miss the truck bed a lot.
