Heating / 240v Inverter - how long does "Ready" mode last?

I bought an ex-demo Peugeot e-Traveller Allure in October and intend to put in a modular kitchen / storage / fold out bed utilising the original rear two seats. I'd hoped to use the HVAC system to maintain the temperature whilst camping, and the integrated 120W inverter was an added bonus though I hope to run an small induction hob so a separate inverter and / or battery storage would be required.

Due to various medical emergencies / work / Christmas I haven't been able to spend as much time looking at this as I'd like to, but it appears that the car disconnects the HV battery when in park for a (relatively) short period of time - around 10 minutes. On two occasions it lasted longer, first time was 1 hr 30 minutes when I started at 91% SOC, in ECO mode, in park, with no A/C but charging a laptop on 240v. Second time was 45 minutes when started at 83% SOC, in normal mode, in park with heating set to 18 degrees C, and a load on 240v inverter - in both these occasions, I only stopped the timer as I had to leave the car and do other things. When I tried again below 60% SOC, it only lasted 9 minutes or so, and I've been unable to replicate the previous results so I'm unable to say with certainty under what circumstances the HVAC system will run longer.

I'm slightly disappointed that ECO mode completely stops all heating, whereas on previous EVs I've owned it would only limit the performance. The dashboard gauge for the HVAC only seems to show either full (but not in the red zone) or off (ECO zone) - altering the fan speed, temperatures, or A/C doesn't make a difference other than indicating on or off. Lastly, the range guessometer also seems to be very sensitive, particularly in the tests above using HVAC whilst not travelling - with the range dropping dramatically, even if I then went to drive very economically.

Anyone bought a PSA group van or MPV with camping in mind? I assume there will be similar issues for the Spacetourer, Zafira Life since they are so closely related - don't know if there may be any firmware updates to resolve this (and if they'd be distributed to all models across the group) or a workaround... I already considered remote pre-conditioning but its a limited length of time, and doesn't enable 240v inverter (so I don't know if the DC-DC converter would top up the 12v battery if I used a separate inverter).

Any thoughts or experiences would be appreciated.

Yeah, this is definately doable but not easy. You will need 6 relays. Peugeot uses 4 wire brake pedal sensor, when 2 contacts close, other two open. So 2 relays to brake pedal and two for DLR as they are independet of each other and two for rear lights.
Will disconnecting the lights not cause fault codes if the BCU thinks they are bulb failures? Might need realys with changeover contacts and switch in a resistor?
