Decorator Industries Inc., a supplier of interior furnishing items to RV industry OEMs, reported lower earnings during the first quarter despite a 16% increase in sales to RV industry customers.

A lower order volume from manufactured home builders, according to Chairman William Bassett, offset the company’s increase in RV-related business.

Decorator earned $581,000 during the three months ended April 1 on sales of $13.4 million.
