12 volt questions

My shuttle bus has a wheelchair ramp and an extra battery. It also has 12 volt plugins at each seat. Wood changing the batteries two deep cycle batteries and adding more batteries be enough to Boondock for a few days without running the bus?

Also could I use small inverters at each 12 volt plug in to run a few small AC appliances?

This is a "How long is a piece of string?" question.

This article (not by me) is a great place to start working out your power needs:

OK. For the sake of ending this constant over thinking. My power needs are minor. For major power hogs such as air conditioning I will use a generator. I'm talking to run all of my electronic stuff and some fairy lights.
And even if I wanted to run something huge wouldn't the battery bank from the truck be able to run a 5000 watt inverter if it were running?

Planning for your needs is not "over-thinking". It's doing the right amount of thinking and preparation.

If you wing it, you will either spend too much money or run out of power just when you need it most.

Spend a few hours doing the calculations, it could save you a fortune (and a 5000W inverter is not cheap).

5kW, by the way, would power many homes Your batteries wouldn't last long driving that beast!

A 200 Amp alternator produces around 2400W, and some of that is required to run the bus and charge the batteries. So if you put a 5000W inverter in the system, you would be draining the battery fast, and probably killing the alternator.

If your needs are very modest, you could probably run it all from 12V, and a couple of deep-cycle batteries would last several days.

Seriously quit it. If you don't have an answer then don't reply. What is it to you if I spend a million dollars? You my mom?

Sorry but seriously, you need to ask a specific enough question to get a useful answer.

List the devices you want to run, for average how many hours per day.

How will you be recharging the bank?

Then we can give opinions on how big the bank needs to be.

Some people thing running a little fridge or a bunch of fans is a small load, others mean one smartphone and a clip-on LED light.

Do you plan to use solar?

Carry a gennie?

How long driving spells, how many days stationary?

How many days between shore power?

I gave you an accurate, and helpful answer.

I won't give you any more.

You're welcome.

I would consider separate systems for your living needs and starting your bus. If you accidentally leave something on or just miscalculated your usage your bus won't start! At that point you will need a jump start.....
