The pile em high sell em cheap (after building them cheap) mentality is why they have been NZ`s best selling light truck - think Toyota Corolla... I`ve driven quite a few (big and small Isuzus) never by choice.
I`ll take your word for it on Isuzu powered landies, but I can`t say that my old 2a with the B vibrated much more than a normal series landrover, and it would cruise at 100km/hr all day.
