He said the theft was a complete shock. The trailer had been parked up on a quiet cul-de-sac for a few days after he went through a health procedure that left him temporarily unable to drive.
He thought it was safe but when he went to leave the house around 9am on Saturday, the trailer was gone.
"It stopped me right in my tracks," Lunn said.
"It just makes you feel sick, that invasion of your privacy, that someone is helping themselves to your stuff."
His stolen trailer was a "brand new" 3-by-5-metre caged Tufftrailer and he was "always getting compliments on it."
He had filed a report with the police and an insurance claim.

Lunn said he had never asked for anything in return from the people he helped.
"All the things I do, I do it for a smile really. It's a huge reward."
"People ask me why I do it, and I ask them, 'why aren't you doing it?'"
