Now they have the answer and they're hoping the public will help them make it happen.
Jeff Bunker said friends of Dylan told him that his 17-year old son wanted to be cremated.
"And he wanted his ashes scattered at North Beach in Coronado and that he wanted the rest of his ashes spread at the North Shore of Oahu," Bunker said.
The driver of the truck, Jonathan Fisher, 17, spoke publicly for the first time during an interview with NBCSanDiego.
He said he lost control of Dylan's truck on Glorietta Boulevard because the road was wet. He feels tremendous guilt for what happened to Dylan.
"I can't even describe how much I miss him," Fisher said. "He was my best friend in the whole world."
Dylan's friends want to be there in Hawaii when his ashes are spread during a paddle out ceremony next March.
"It'll mean the world to me to be there for him, he would love it," said Fisher.
His parents have set up a memorial fund to help pay for the friends who can't afford to go. Anyone who would like to help out can go to any Wells Fargo Bank and donate money under the "Dylan Bunker North Shore Paddle Out Memorial Fund."
