Only if it is an Prius or similar vehicle that has climate control. People have mounted small window units in vehicles and powered them with a generator. This is possible in most motorhomes with generators as well. Best and cheapest way is to live and stay in moderately cool climates so AC isn’t necessary.

Can look for the smallest portable A/c unit, but you need your batteries/energy/solar setup accordingly, this will cost some. Can find 700 watt units.
There are also swamp/evap cooler type small portable units sometimes called air coolers, some of which run off 12v dc, they requre much less energy (I think 50-300 watt range) but they dont bring temperature down as much as a/c.
If you are doing really good battery setup anyway you can just run rv/van roof a/c which can be down to 850 watt usage and get a used unit. "Cheap" setup is going to be evap cooler

The evap coolers don’t work in certain climates very well and in the ones they do require a good water source.

Well people fulltime using them in hot climates even out east. The OP wants cheap that's a cheap option. With clever use of fans.
Moving around with the weather is what I do year round and it does not prevent hot parking lot time. It can be a week of 70s then a 100f. Which reminds me need to order evap cooler myself today.

Why not use a 12v vehicle a/c unit like the rear unit on an ambulance? They're self contained with nothing out the top or sides like POS MHs use. We have dozens of RV surplus stores not far & I'm sure RV wrecking yards also.

Your vehicle probably already has an AC system - and most van ACs include back cooling.
You can replace your engine belt-powered AC compressor with a 12v version like in EVs.
The power to the compressor and fans can be attached to a switch to select running from the alternator when driving or from house batteries when parked.
Electric compressors cost $300 and up. You will need someone competent with custom vehicle wiring to set up the dual-mode power.

There are also "complete" systems that are designed to be usable when the engine is off:

Unless it's humid, a small swamp cooler would work well. There are many available for cheap.

Better just buy an ambulance, there is one for sale, just sayin.
There are plentry of similar 12v van unitsall these roof ac, whatever one may call them, will draw good wattage, need to pay for power setup so not "cheap" really. Ambulances idle a lot so they can run their ac when they need to, a camper van will need good solar and extra battery setup
