A first printer for van life
Build size, power, an enclosure, and how fiddly it is. Criteria for a first machine, not a ranking.

Size it to the parts, not to a brochure
Most of the useful files are small. A cup holder, a door holder, or a water inlet funnel has to fit on the bed with a little room around it for the nozzle to travel. Measure the largest part you actually expect to print, then compare that to the printable volume on the spec sheet, not the outside size of the machine. A huge printer is a hard thing to store in a van.
The machine also has to live somewhere while you are not printing. Look at the footprint and the height with the lid or the spool on. A separate look at machines and the numbers published for them is the printer buyer's guide. This page stays with the criteria.
Power, read off the label
Do not trust a forum guess for watts. The label on the printer, or the power supply bolted to it, is the number that matters. Compare that with what your inverter can hold continuously, and with what the fridge is already using. A heated bed is usually the hungry part. If you only intend to print PLA and PETG, you may not need a machine that also heats a chamber.
How that load sits on a house battery is covered, without a shopping list, in running a printer on the road. If you do not want to own a machine yet, getting a part printed is the other route.
Enclosure, and how much fiddling you want
An open printer is enough for PLA and for a lot of PETG. ASA and ABS want an enclosure so the part does not peel off the bed, and they want a way for the fumes to leave the van. You can add a box later. Buying an enclosed machine is the simpler version of the same idea. Neither choice is a brand. It is whether you expect to print the outdoor parts in vents and fans.
Ease of use is the rest of the first-machine question. A bed that levels itself, a filament sensor, and a screen or an app you can actually follow will matter more than a top speed you will never use. Watch a full print, not a highlight reel, in the videos. Then decide if you want that process in the rig. Material choice for those prints is PLA, PETG, and ASA.
