If anyone's unfamiliar with what I'm talking about, it's on page 179 of the Gamemastery Guide. There's no picture, but based on the stats I think it's either a giant robot or tank like thing.
Steampunk metal wagon, w/ flamethrowers.
So same role as a tank. "Rare" likely due to filling a narrow niche.
(Now imagining an invasion led by these!)
For a picture, look up the RPG Deadlands; it has several tanky, steampunk vehicles, often armed.
Pretty sure it's a giant robot. Or at least comparable to a battlemech.

Or maybe the Tundra Tank from Avatar if you want something more fantasy tech.
A mech would probably have arms and a melee attack. This looks like a steam wagon with a turret.
Well I don't know about the PF2 version, but the Pathfinder version from ultimate combat definitely has legs.
This thankfully rare and expensive walking monstrosity is one of the more bizarre land vehicles in existence. A giant cauldron of iron atop stubby but effective legs, it hobbles its way across the battlefield at a grinding pace. It costs 100 gp in alchemical reagents to fuel 1 hour of activity. Creatures inside the steam giant gain either total cover (in the lower decks) or improved cover (in the upper viewing and control deck). Only the upper deck has view ports, allowing those inside the steam giant to look out.
Propulsion alchemical (10 squares of alchemical engines; hardness 8, hp 200)
Driving Check Knowledge (arcana) or Craft (alchemy) +10 to the DC
Forward Facing one side of the square vehicle space
Driving Device two levers used to move the legs
Driving Space a single 5-ft.-by-5-ft. square that contains the two levers that serve as the steam giant's driving device; these levers are located on the third (top) deck of the vehicle
Crew 4
Passengers 6
Decks 3; The two lower decks give access to the alchemical engine that powers the steam giant. These lower decks have no windows or other way to see outside of the vehicle. The upper deck is an observation deck that contains the alchemical giant's driving device and driving square.
Weapons 2 Large direct-fire ranged siege engines on the arms
Thinking about it, it probably looks like an open-topped urbanmech
I envision it being somewhat more like:The Revelator Colossal Warjack of Warmachine.
I am always down for more steampunk walking battle-mechs.
We have two options, it's either a a vehicle for a Steam Giant or a giant vehicle powered by steam.
Personally, I prefer to imagine that there is steam powered giant vehicle for Steam Giants.
