Although you have mentioned removing the camper to (occasionally) use the flatbed, I think you would be better served by planning to leave the camper "permanently" attached.
Doing so might let you (go through some steps and then) register your rig as a motorhome, which might reduce registration fees and/or insurance fees.
Doing so would make it easier to have a pass-through from truck to camper. You might consider replacing the truck-cab's rear-window with an aluminum "frame". Essentially a piece of thick aluminum, with a hole cut out of it and a lip (for attaching a boot to your camper) welded on, that replaces your rear-window. When planning this, keep in mind that your rear-window (and windshield) are part of your rollover protection.
Doing so would allow you to bolt the camper body to the flatbed without having to worry about insects/water/... passing through the holes when dismounted.
While you are planning your under-flatbed boxes (for snowboards, tire chains, vented propane lockers, vented generator lockers, warm-weather water-jug lockers, ...), contact the manufacturer about also adding bolting points for your camper. It will likely be faster and cheaper than designing a fully custom flatbed.
If you want a pass-through, make sure to plan enough space in the "headache rack" of the flatbed.
That's the direction I'd been leaning (well, not so much the window piece, but a semi-permanent camper that can be removed).
I searched this forum but came up a bit short. How are those bolting points designed/attached to the camper itself? Are their external brackets? Are they under the floor boards? Something else?
