Years ago all of Holden's brochures on utes had hay bales etc. pictured in the tray, but then they realised that most young blokes couldn't afford a Monaro when they were reintroduced, so the easy 2 door option was to spice up the humble work horse and slot a V8 into it and hey presto an instant go fast machine that looked cool.
If you look back at what the market was doing the VS only had a 6 Cylinder "S Pack" as a model, with the V8 only being an optional upgrade and no SS in the utility line up. The sports type of styling was brought in with the introduction of the VU during VT and VX production, coincidentally around the same time as Monaro was reincarnated.
It was never designed to be hauling 44 Gallon Drums or pallets, that market was re-allocated to the Cab Chassis format (1 Tonner) which is what all the Japanese style utes were doing and who originally stole that highly practical market from both Holden and Ford that had the outdated style body ute trays.
