If the interior is 6 feet wide, I might just take the back seats out when I go camping and set up a plywood bed in the rear with some drawers underneath for gear. The front seats would just slide forward.

need something like this from overland addict

puts me in mind again of the CT bed length discussions - I just don’t see how anyone fits/sleeps back there. The CT cabin on the other hand…

This is in the ballpark.

My big concern with the vault is climate control. Doing temperature control on just the cabin is a lot easier than cabin + vault.

LOL Of all the times I have gone camping I never thought to bring an air conditioner. CT bed with some air mattresses and a pop-up tent would be very nice to drive to the trailhead before heading out with a pack.

Don’t they have to treat the vault as a separate temp controlled area from the cabin? Most of the time the vault can just be ignored (ex: hauling things that prevent the tonneau from closing). It’s just when the dog or some people are occupying the vault and there is enclosed airspace (tent, tonneau closed, etc.) that you would ever want to heat/cool the vault area. Well, unless you are trying to make it a refrigerated vault for hauling items that can spoil.

another (big) concern with climate controls in vault is: with the tailgate up, vault won’t hold many of us. Can prob fit sleeping at a diagonal, but that’s a pretty limiting solution, and never the most comfortable orientation.

Not to mention the shape of the vault’s “ceiling” when closed does not seem a terribly spacious place to be.

At some point, with vault closed and tailgate up aren’t you winnowed down to the sleeping footprint of an ultralight trekking pole tent?

I just don’t think a lot of that’s happening in just this space, and with these odd angles.

Mostly I agree with you. But I’ve had a few times when I’ve gone camping and didn’t expect sub-freezing temperatures or just wasn’t planning on camping and don’t have the appropriate gear in the car. It is exceptionally good for impromptu camping.

Though one time I was completely exhausted after a couple of days of riding and about ready to pass out, but needed to hang out for a couple hours still, so I put it in camp mode and took a nap in the back. Works a charm.

I doubt the vault will be insulated at all, so it will never be as easy to cool/ heat as the cabin. The metal sides of the truck will conduct the chill from outside air directly into the truck bed.

Going camping in my Sentra was pretty chilly. My toes got super-cold, despite extra blankets. But my gear wasn't rated for freezing, my current gear is.

Thermal conductivity of Stainless is much better than aluminium, and glass better than stainless. Most of the cabin "insulation" would be from the structural pack and sound deadening materials in the voids, and carpet. Technically the rear seat backrest form a barrier, but a closed vault cover will also help the cabin. Quilted internal window coverings with Aerogel would work a treat. You could do the same for the vault.

Simply: Cabin is designed to be climate controlled. The vault is not.

Well, JBee is pointing out that the cabin is surrounded by glass, which has higher thermal conductivity than the stainless steel enveloping the vault. Thermal conductivity is bad for climate control. Tesla has proven they can handle this because all of their cars are glass boxes, but it must’ve been a challenge.

?: Anyone plastering their windows with “quilted internal window coverings with Aerogel” will have to completely trust FSD

I get it. But it’s not that simple.

It’s not simple single panned glass, it’s laminate with an insulating layer. That’s why you don’t cook inside the car even though it has a huge glass ceiling. The stainless sides, not the vault cover are designed to block heat the way the glass is. Likewise the rest of the interior is designed to retain heat to keep the energy cost of heating/ cooling the cabin to a minimum.

So to be clear glass is a better thermal "conductivity" insulator than stainless or aluminium, but is mostly IR transparent, meaning heat can radiate out through the glass from anything that is warm inside. There are three forms of heat transfer, convection (air flow etc), conduction (material transfer) and radiation. All three forms need to be addressed for proper insulation.

So in the case of the stainless and aluminium they will block or reflect heat radiation, depending on their surface preparation, with smoother and shinier surface being more reflective of light and lower frequency heat radiation. The glass will let the heat through unless it has a filter like low e glass in households, but even then it will have residual emissivity that can and should be blocked with a shiny foil backed insulated window cover, to stop heat radiadiating out from black surfaces inside the CT. Especially on the CT where about 40% of the exposed area is glass. And another reason for a light interior colour.

Thermal conductivity of glass is actually pretty good in general compared to metals. Glass is 1, Stainless 14 but Aluminium is 237. That will essentially get the heat through the CT skin, where convection of air on the outside will either add or remove heat to the interface layer on the outside of the vehicle. The amount of heat exchanged at the surface depends on the mass flow (wind) and temperature difference to the inside.

Air (which is mostly nitrogen) is a good insulator (0.02) so even just trapping air against the glass helps reduce conductivity. Rockwool insulation mats work on the same principle in that stopping microcirculation of air through a otherwise hollow mesh of material, also means that heat convection is minimised. So the thermal conductivity of the air in the spaces is actually creating the insulation properties, not the insulation matt material itself. It's just used as a container to hold the air still, to stop convection. This is also why you will see mats with a reflective layer for blocking radiation.

So the ideal insulator is actually aerogel (lighter than air solid with microbubbles of air), AI it offers the best thermal resistance for its thickness. It's also used for catching micro asteroids without destroying them.

I've often also wondered if Tesla will integrate heat recovery ventilation to reduce HVAC consumption and improve air quality.

For snow dwellers, ,maybe set preheat mode for the battery for a bonus warmer bottom.

That's a super weird looking angle, makes the truck look crazy long
