I am not sure if i should start a new thread for this, so please let me know if posting here is inappropriate....
I have the same desires for better organized bed due to the need for interior bike storage as you with my 2015 Tundra double cab and Flippac.
I haven't seen a single photo on the internet of a flippac with bikes inside with any sort of organization drawers or benches built in... and definitely not a thread hijack.
Also, I've drawn up the Goose Gear and Scout Equipment type setups, I don't that working with a pickup bed. If you haven't seen it, I think bikes inside plus a DRIFTA kitchen DPOR would be ideal... in a pickup with a flippac you could also throw a shower on the side, lots of water inside, along with a loo for midnight nature calls.
I have a T100 (same bed as your Tundra) and a Flippac...I left a 30" aisle open so that I can sleep there when by myself or haul stuff. I would think a 30" x 6.5' space could accommodate two bikes.
Hey Arclight, I followed your posts for years when I had a T100! We did think of a center aisle... but our default is to leave wheels on. So, as we're used to it, bikes go flush against the passenger wall and still have handlebars wide enough to stick out to the center and snag you as you climb up and down from the loft. I'm definitely going to include a center aisle option when I do some quick mock-ups with 2x4s. The idea I am most curious about today is bikes on a slide, front wheel off, handlebars turned 90deg. It's wierd, but I saw a sprinter pull it off perfectly - besides pedals, each bike was super narrow and stabilized with a rear wheel hook. That's the other quickie 2x4 project to fit check on my list.
A friend of mine shared this on Facebook, and I thought of your thread. It was designed initially to carry the bikes, covered and secured and then they expanded it. Food for thought.

Haha, yep - seen those along with bags for bikes on hitches. I think that or a small trailer (scamp/casita) would be rad if we camp 4 people (munchkins), but for today we can actually fit everything and still have some room, but I just can't figure out the organization that makes it fast and easy.
Also, it's snowy here and I just got a set of Icons to put on... definitely not zero progress, but not much in the storage direction!
