The disadvantages of the OTJ comes from its jeep military origins - good for hauling heavy loads off-road but over-designed for civilian on-road use:

1) cramped seating position for the passengers at the back (because of short wheelbase).
2) heavy ladder frame.
3) crude solid axle (front) and live axle (rear).

In a way, past utility vehicles such as the Mini Moke and the Sakbayan were more advanced than the OTJ. Both had 4-wheel independent suspension and more comfortable seating for the rear passengers. The Moke had a box-section frame with front and rear subframes.

So I see the future OTJ as not for extreme off-roading but more for on-road use with good highway performance but will be capable of running on rough provincial roads and flooded city streets. It should be comfortable for long distance travel.

This may annoy the jeep purists but here goes. I'd like the future OTJ to:

1) be based on a front-wheel-drive car platform with longer wheelbase. The front engine, rear wheel drive Toyota Avanza platform is also a possibility.
2) have adeqaute ground clearance and 4-wheel independent suspension like a Honda CRV or Toyota RAV4 (live rear axle in case of Avanza platform).
3) have a box-section frame (lighter than a ladder frame)
4) be built as strong as a VW Type 181.
5) (while we're dreaming, we might as well go all the way) interconnected suspension like the Citroen 2CV ("able to drive across a ploughed field without breaking the eggs it was carrying") and the Africar.
