If the tailgate is down when the tent is deployed, how my stuff won't be stolen while sleeping?

Why not automatically inflate with air compressor from CT?

the Ct compressor isn’t available to anything other than the air suspension

On thing - it's not possible that the CT's heaters were not efficient enough for this tent, as that is a heat pump

the point wasn’t that the heat pump is too “inefficient” to heat the tent

it’s that the CTs heat pump is overkill, and it’s too inefficient to condition both the tent and the cabin using the heat pump when sleeping in the tent only requires a small aux heater


it’s at this point someone says “but Tesla could have instead engineerEd X, Y, Z”

but that they didn’t shows it wasn’t a commercially viable alternating for either Tesla or the consumer

like how people who need an aux air compressor can buy a great small portable 3rd party one for $150 instead of Tesla engineering the aux compressor guts (and maintenance) into the CT itself

I understood that and have to disagree. Heat pumps "move heat from one place to another" while a "small aux heater" just uses electricity to heat an area. A heat pump may be 10x more efficient per watt.

"10x more efficient" is not "less efficient"

4) I asked why not use CT's heaters -- he mentioned that CT has inefficient heating when compared with a local electrical heater. (entire vehicle vs tent)

On thing - it's not possible that the CT's heaters were not efficient enough for this tent, as that is a heat pump.

I understand at a high-level that heating the cabin and the tent is a larger volume ... but it is hard to believe that using the CTs heat pump would be more [IN]efficient than a 120v heater. ie. CT heat pump more efficent.
UPDATE: inefficient

Oh neat, there's a sliding cover for the cup and phone holders.

Not on the production ones I'm afraid. That must've been a beta proto they used for display.

Air compressors are very slow because they are designed to operate at 30-40PSI.

How the long does it take to setup and take down the tent?

I need some outlets, Harbor Freight, and my trusty Kentucky hillbilly blood to get it done.

See, see what I did there - I'll be going to Harbor Freight because, you know, a beast will have stolen my wallet

heat pumps alao use electricity to “move heat from one place to another”

regardless, I think you might be missing the all-in net “inefficiency” being considered here

you might design the truck to have HVAC ducting to the vault (no small order), and now the “inefficiency” of using the heat pump isn’t merely about the efficiency of the unit itself, it’s about the net inefficiencies of that HVAC ducting design plus the cost of incorporating that ducting into the overall blueprint of the truck, incorporated into every truck built, but utilized only in edge cases.

so, even if a heat pump is 10x more efficient as a unit, incorporate the ducring Inefficiencies now you’re down to say 7x, then look at the manufacturing plan of building that system into 99 trucks that ~never use it for the benefit of every 1 truck that will.

I can only assume it’s this sort of all-in, manufacturing level, net inefficiency that’s being weighed here. That’s really the only level Tesla calculates at.

FYI Roybi has a low pressure battery operated hand-held compressor.

I finally understand what the pump pictured in the rear under-seat storage is for: tent inflation.

and besides. There is no good way to get the heat from the cab to the tent.

Gonna shove an electric blanket into my sleeping bag, plug it in to one of the bed outlets and call it a day.

FYI, there is this contraption (apparently well built but not cheap).

yes, this is the other option to “inefficiently” heat the whole interior+tent, and “inefficiently” duct it between the interior to the tent

I’ve not used one of the above, but I suspect there’s some fan system at the tent side of the duct that attempts to draw the cabin air up into the tent

this might work out sort of like having your home thermostat in your living room, running a duct to your garage, then trying to temp balance - to get it 70° in the garage, you have to set the home thermostat to 90° because it’scolder ambient in the garage, but with no thermostat (or separate zone) in the garage the HVAC unit can’t ‘see’ that it’s colder in there

I do not think the temperature analogy is the major factor that is in play here ...
I think it is air pressure. The cabin interior is well sealed and would hold pressure *way* better than a tent with zippers and 'fabric' seams. My feeling the air pressure would make air flow from the cabin down the tube into the tent and then outside. Of course, I do see how the cabin interior where the temperature sensor is would stay warmer so you would have to have the temperature higher like your example. I just don't think it is a big of delta as you I think. ie. 80 vs 90
I'm sure this company did a lot of 'backyard' testing. I recall Munro doing an ad-hoc review while at some event, for what that is worth.
