THE man behind the resurrected Roadstar brand of caravans has come out fighting after allegations that other manufacturers are rubbishing his product.

Angry Victorian businessman Ken Nizam is now threatening to take action, warning: "Any negativity will be taken very seriously."

He has accused a salesman for a major Australian caravan manufacturer of attempting to tarnish Roadstar's reputation at a recent NSW show so he could secure a deal with a potential customer, who went on to buy a Roadstar Tamer caravan.

Mr Nizam has now taken his grouse to the Recreational Vehicle Manufacturers Association of Australia.

In a letter to the peak body, he said he still respected the company's owner "regardless of how they conduct their business and how they go about trying to squash others".

He wanted "dishonest sale people and manufacturers to put a stop to nonsense and disgusting rumours".

Mr Nizam revealed that the buyer was so satisfied with his caravan that he wanted to buy into Roadstar Caravans.

"I have worked hard to resurrect the business, moving forward with solid steps and many ideas that I would not consider to sell or accept shareholders in the business," he said.

Mr Nizam said manufacturers moved in different directions and quality.

"I am not like other manufacturers as I believe in fair play. To rubbish another product means you devalue your character, pride and product."

He added: "They fire bullets, I fire roses!"

Mr Nizam bought the original Roadstar Industries' plant and equipment when the 21-year-old company went belly-up in 2009 owing $1.3 million.

The Australian Hitec Engineering director also won the right to use the iconic Roadstar and Compass trademarks, which now appear on his range of quality caravans.

Mr Nizam, whose engineering company supplied chassis to the original Roadstar manufacturer, told Caravanning News that some other caravan builders were now attempting to muddy his achievements in bringing Roadstar back from the dead.

"We were quick enough to purchase the complete history, trademarks, computer programs, including templates, machinery and equipment. There is no rhyme or reason why certain parties now enjoy gossiping and talking down Roadstar," he said.
