In Thailand, every older model pick up truck was very commonly made into "station wagons". You don't see it "much" on the new models but tonnes on the old ones. I have seen trucks just like the one pictured before although they aren't that common just because they are so old now.
Thailand has a huge tax on SUVs making them way more expensive than pick up trucks, so this "wagon" may be a loophole to getting around that.
I think that a lot of them were made this way from the factory but the Isuzus are often badged as Thairung which must be the factory conversion company. Do a google image search for "Thairung" and you'll see about 3 generations of mostly Isuzu truck station wagon. Over here the Isuzu Dmax is the same as a Chev Colorado so you will see a lot of Colorado wagons as well.
I have never noticed badging of any other company on the Toyotas or other Japanese wagons.
