They didn't have to do prototypes - but they did have to make sure it works.
Consider a typical COPO - a special wheelbase truck to mount a custom bed. They would make sure the wheelbase was doable and would support the weight. And figure out the driveshafts and pricing. All on paper, all for one sale.
