I recall when I was still doing my FS back in college... while interviewing Jeepney Makers and Local (provincial) Owner Type makes / assemblers - I asked them why the owner type is made like so?...
They answered... basically... we need to maximize 5 pcs. of 4 x 8 G.I. Sheets to form 1 body. The Front fenders are made like so because that shape is the most practical configuration left for whats going to be left over of the 5 pcs. of sheets of metal.
The Tub is shaped like so because it eats less from the set of sheets of metal.
The Cowling and firewall were also very minimal and simplistic.
The only strength an OTJ will have is its chassis which basically where everything is bolted onto.
It was actually the formula introduced by the americans when they built the first General Purpose War Vehicle... hence G.P. - Gen. Purpose... GP = Jip/ Jeep.
The first jeep has a folding windshield assembly which safely collapses on the two rubber blocks near the front of the hood; This feature allows the Jeep able to cross through jungles and dodge low tree branches... as well as accommodate long bulky cargo like war weapons.
When Sarao adopted or costumized these war jeeps, He basically kept everything and slowly improved the shape and configuration through the years. The last Sarao was longer, with more fixed body and windows and plenty of Stainless Steel Garnishings. Making one is more costly than making an normal car... since every bits and pieces would undergo - Time-and Profit siphoning activities like, BUFFING and Detailing. Buffing Stainless is plainly a Greenhouse gas generator. Using a Hi-wattage Grinder with a buffing pad and or abrasive grit and some buffing paste takes many man hours to complete a set of panels.
But the market seems to take this as an essential element to make the OTJ highly desirable, thus the tradition proliferated for many years. It is still very much alive in most provinces like Imus.
Basically, the cost reduction took place on the quantity of materials used... but the drawback is on the amount of time and work process invested in making it look shiny and attention grabbing.
