2014+ Backseat Help

i did an intro earlier today in the new member section, but I wanted to throw this out here in this section as welll. See below.

My question to all of you is, does anyone make some sort or angled rubber block that will help make the back floor flat? I'm looking for something like this for my dogs soft kennel when we go on long trips. His kennel definitely fits but I have to adjust the seat to somewhat pitch it in place so it doesn't rock, and even then I'd like something underneath where the kennel drops off so he doesn't puncture the floor of the soft kennel. I have thought about just throwing and old pillow under there, but the flat back surface would also serve for other purposes too. Any suggestions???

Thanks guys!

 

I have never seen nor heard of any product like this. However I have built small simple lightweight platforms for equipment in the backseat of my work truck which I use mostly as a mobile office. I mostly use 1x1 rips and 1/4" plywood. Scribe and trimmed to match the seat or floor on the bottom edge the platform can be made flat and stable.
