Dog transportation in an access cab or double cab?

Glad I searched. I was looking at goosgear, but Im not sure. I want something custom, and they didn't seem too keen on building my idea. I'll make my own platform I think. I also wanted a stowable slide in and out ramp from under the platform. THEN I want tie downs for the dog crate. If we rollmover, I want my German Shepherd Kane to be contained. Starting to think I'll build my own dog crate too. Just can't find exactly what I want.
I make all sorts of things so this shouldn't be bad. Bladesmith, metal worker etc. Great thread.

 

I like this idea. Sort what is was thinking of doing with my 2nd Gen extended cab. But then got the DCLB 3rd Gen. Got the 4 door can pretty much for him.
