New function for the old Pick-up truck

In the first half of the seventies there was a Ford Pick-up truck, in which there was a lion under a plastic canopy. Yes, it was the so called Wild Life Truck with Rola-Matics function. It was the same model, like the Kennel truck with the four dogs. The big problem in the present days, what sould we do with this pick-up truck without the lion and canopy? Well, this is the question.

(This picture is taken from the internet, as an illustration.)
At the end, I think, I found a proper solution! It shell deliver small barrels! They are stuck onto a plastic plate which is fixed to the car. The part of the Rola-Matics function, the yellow disc is removed before I fixed the plate with the barrels.

It is obvious, that this way the Rola-matics function doesn't work (let alone the fact, that I bought it in that condition).
