My other comment got long-winded, so I’ll just comment again:
You could save yourself the majority of the calculations by using a monitoring device, brand named kill-a-watt.
You can plug your AC directly into this device, plugged into power, and it will keep track of your consumption. Your friend’s electric bill will show the price per kWh, so all you will need to do is take your actual kWh value you measured on your monitor, and multiply it by the cost per kWh. Round up when you pay your friend, and tell them thank you 🙂
I use this one in my Sprinter: https://smile.amazon.com/gp/product/B000OTIPDQ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
That plus 100W of solar on 200Ah of battery and we've been all good with a diesel furnace, fridge, water pump, and a few other things.
Looks reasonable to me. Some thoughts:
The Bluetooth version of that controller is $3.05 more and will keep you from having to buy ~$30 external display. Makes checking status and configuration much easier than using the controller's native controls.
If you haven't spent all the 2nd stimulus check yet :-) I'd consider adding a 20A DC-DC charger (alternator charging) to the mix. Renogy makes one for about $100 if you want to stick with them. Between solar and alternator you'd be set for power. The 20A limit will help protect both the lithium and the alternator.
If you will be camping in the cold I'd consider heat tape or something to keep the LFP above freezing. I don't think the BMS will handle cold cutoff.
if you already own a drill, get one of these and some small tubing to get it pretty much dry..... how I clear all the water out of a toilet when I am lucky enough to have to change them out.
I'm in the US so I'm not sure if they ship to you, but I bought this folding mattress for my guest room and it gets rave reviews from everyone. Cheap, folds up and works as a little bench/sofa when not in use.

I use these in my school bus and they hold well and have had no rust or wear issues.

Get one of these for cooking on / in. They're meant for cooking whilst fishing but they're so incredibly versatile, they're amazing for the little stove tops in a campervan

Just an FYI - You can't use the standard isolator for lead-acid batteries to charge LIFePo4 batteries (Jackery). You will need a DC-DC charger for that. https://www.amazon.com/Victron-Energy-Orion-Tr-Non-Isolated-Bluetooth/dp/B086Q8YNJZ/ref=sr_1_4?crid=21LQORUQ16NJ&keywords=dc-dc+charger&qid=1646669483&sprefix=dc-dc+charger%2Caps%2C121&sr=8-4
> I can turn on the switch to start the charging and turn it off to stop it. The problem with that is my brain can sometimes fall out and I may forget to turn it on or off
You could automate it with a low voltage disconnect. Mine looks like this^1 and was ~$8 a couple years ago.
^1 quick example, not necessarily a recommendation
^2 or model whatever VSR behavior you want to mimic
I dunno what the problem is, just get a 12V to 230 V converter. They plug into the standard 12V port and turn out into the regular socket for power so you can just plug in your regular charger. Obviously it's a bit of a drain on batteries so I suggest to use it mostly when the vehicle is in motion or freshly charged up. If you are using it heavily it might start its fan that can become rather loud sometimes though.
Yes, 2020 13" mbp m1, base model.
Charges slower than the standard charger, but as I can plug it in to charge anytime I’m sleeping or driving or hiking etc, this has never been an issue for me, especially with the battery life on these things.
I also tried replacing the 12V car charger sockets with this dual-USBone, but... despite claiming 63W (and 36W?) it could charger neither my MBP nor my iPad.
Super simple. You need a) a 12V socket, and b) one of these to plug into it:

I’d just buy speakers like these and install like a red/black speaker wire port… for the outdoor sound.

Maybe you can link me the kind you recommend. A lot of these are showing self adhesive and I’m not too keen to put staples in my car :/ thank you!!
I would upgrade the charger unit but very basic and easy install!
The 40a is a bit above your price point, but unless you're driving a lot, I think the 20a will not be sufficient. It depends on how much power you plan to use daily. It'll take you about 6 hours to charge that battery from 50% discharge to full with the 20a.
You're looking for something like this.
What does the inside look like? More for privacy or blocking the sun? What are the dimensions it needs to cover?
My wife and I are probably a couple of years off buying a campervan, however you have gave me some ideas how we can convert our Vauxhall Zafira (MPV with fold down seats) in to an interim camper for overnight/weekend trips out. Be interested to know whether you have considered anything to cover the back such as: https://www.amazon.co.uk/dp/B01NA6NXB3/ref=cm_sw_r_cp_apa_u4E9Bb5M16865
Many thanks for sharing.
