Recreation vehicle and bus maker Thor Industries Inc. today (May 4)  said fiscal third-quarter sales fell 41% on steep declines in RV volumes.

Overall sales for the quarter ended April 30 fell to $415 million from $708 million last year. RV sales fell by nearly half to $311 million from $601 million, while bus sales slipped to $104 million from $107 million.

For the first nine months of its fiscal year, sales fell 48% to $1.08 billion from $2.07 billion. RV sales plunged 56% to $766 million from $1.77 billion during the period, but bus sales inched higher to $305 million from $300 million.

RV makers like Thor have been hit hard as consumers have put off sales of the discretionary vehicles amid shrinking home values and rising unemployment.
