There are big jeeps and little jeeps. The big jeeps are the traditional refurbished American army jeeps - sometimes called sarao
after the now-defunct Manila workshop that originally made this type of jeepney - or the newer Isuzu trucks.
The smaller ones are a Cebuano invention called multicabs.
This was originally - and still is - the name of a company in Cebu (on A S Fortuna in Mandaue), which first started importing used mini trucks from Japan. With an engine displacement of only 660 cc, these vehicles are called keitora
("light trucks") in Japan and are used mostly for deliveries or hauling plumbers and their gear.
In Cebu we dress them up, make 'em look real nice, and use them as passenger jeeps or as pickups for ferrying the family to the mall. In fact, this has developed into an industry; Cebu exports multicabs not just to the rest of the Philippines, but to places as far away as Cuba.
The thing is, these vehicles, as well as the larger trucks, originate from Japan, and, as such, are right-hand drive vehicles.
