He had been dropping off some freight in the area and had decided to stop in at the event, which also offered kids the chance to ride a big rig as part of a truck convoy.
Not expecting the win, Mr Burling had almost missed the judge's announcement.
"I didn't quite hear him, and then he called out Burling Transport and I was just overwhelmed. I couldn't believe it."
The trucks were judged on the cleanliness of the chassis, cab, tyres and curtain sides.
Mr Burling, who has been working in the industry for 25 years, said there was "endless polishing" and a whole lot of work involved in keeping the truck in top condition.
He cleaned the truck most nights, seeing it as part of keeping up a good perception for the family-owned business.
"It's just image, it looks good -- image is everything.
"You want to start the way you will continue."
Mr Burling's father, Fred, said it was good to see his son's work recognised.
"It annoys me sometimes, him out there polishing it, but it really is a credit."
The truck is one in a fleet of about 12 owned by the business, which delivers freight including wool, timber and fertiliser throughout the country.
The award for best truck included a trophy, certificate and a prize pack with a $1000 voucher from Bay Tyres.
Money raised at the event went towards the Little Elms Charitable Trust, which provides accommodation for families with children suffering from cancer.
