Useable space vs comfort

What does the area behind the seats in a MX5 Miata NC PRHT look like?

In my research the 3rd brake light on PRHT models don’t leak in to the boot – they are in the folding roof area which contains many drain channels. There was a forum thread somewhere that was questioning what drains the 2006-2015 PRHT model had so I have taken photos of the area incase someone stumbles upon this so it can help.

The passenger side (AUS), showing the main drain to the left centre with a bit of a grid over it, and many tubes. I have since fixed the carpet up – not sure why it wasn’t correct.
Directly behind the transmission hump. The BOSE amp on the right, I believe it’s the PRHT controller on the left.
The right hand drivers side (AUS) with it’s drain and hoses – I just noticed the upper hose is in a different place to the passenger side so it’s been disconnected at some time. It connects up to a spout on the folding roof mechanism.
Here’s the drivers side view from within the car.

Equipment

When searching for equipment, look for keywords like Hiking, lightweight, and Car Camping. I have gone with the following as a mixture of easy to deploy/pack for one person, and relatively comfortable.

Boot / Trunk

Tent, Chair, One bag, two boxes, table, pump, pegs, cords, hose.

I’m now attempting to attach a nice looking luggage rack, to move at least the tent out and hopefully the chair also as that will give me much more room for cooking utensils and such, and make the whole packing/unpacking experience vastly easier.
