Storage with seats completely folded against back of front seats

Hi. EDITED. I have a 2004 Tundra with the crew max cab. I'm going road trip/camping for several weeks. Don't need the back seats. After the seats are folded up, lots of room. I'm looking for ideas for organizing with or without bins. I can woodwork if necessary.
16" wide x 48" wide by 24" high.
Many thanks.
Budd

I found several more than those two just by using the Search in the top-right corner of the forum a minute ago.

There's a gaggle of information here on the subject.

 

I searched titles and first gen forums only. Then picked only the AC ones because I assumed that's what an "ex crew" was

 

You did good! Didn't mean to imply otherwise, just pointing out, that if @Solaegui needed more than those two excellent threads you pulled up, there are a BUNCH here on the forum with various ideas, built-ins, slide-outs, subwoofer boxes, all kinds of goodies to be had.

 

This is where cab type is so important. The DC rear seats fold up against the back of the front seats as OP's title suggests. However, we have no idea for sure because OP didn't properly specify his/her cab type which leads me to believe that OP hasn't rear the MEGATHREAD either.
