The gallery's trustees are already collecting artwork and memorabilia relating to the truck.
Trustee Marg Morrow said the show would be about people's memories of the truck and what it meant to them.
Anyone could contribute in any art form, including poetry, writing, painting, photos, songs or stories. She expects lots of contributions.
Everyone in Kohukohu had an opinion on the truck, and they were all wildly different, she said.
"One person thought it was an eyesore that should have gone years ago. Another said it represented everything they loved about this place, the way things are allowed to fall into ruins."
Some visitors came to Kohukohu just to see the old truck, including a German man who returned every five years to photograph it.
"He was devastated when it was gone," she said.
