The 10m mural now hangs in King Street Artworks where Dale spends much of his time.
"I was given a long piece of canvas and I had to use it," he said.
Painting "with the local earth", Dale covered the canvas with depictions of trucks he had seen on his travels.
He spent some time in Mt Magnet, at the famous Road House which is the busiest truck stop in Western Australia.
The largest road train he saw had 84 tyres, and he "saw one guy going down 72 tyres reducing air pressure".
The lower tyre pressures would have been needed to cope with corrugations in the road.
"It's tough country," he said.
Vehicles include mining trucks and 3-trailer cattle trucks, sharing the road with tourists and locals in utes, who also make an appearance on Dale's mural.
The canvas work was completed "in short bursts" working from sketches, and painted stretched out on whatever flat surface Dale could find, including picnic tables by the Boab Prison Tree. Along the way, a group of young Australian artists donated some ochre paints.
On his travels Dale also headlined an exhibition in the Anzac Hall at Mt Magnet, as part of the town's annual Astro Rocks Fest, which mingles astronomy and geology.
While in Australia, Dale also checked out the largest public corroboree dancing exhibition, the Mowanjum Festival.
