Winnebago Industries, Inc. (NYSE: WGO) shares fell sharply today after the recreational vehicle maker announced disappointing earnings. The company saw its third quarter profit dive 73% as higher gas prices, tigher consumer credit, and a softer economy drove motor home sales into the ground.

"The motor home market has changed significantly in the past year, with dramatic declines in the past few months," CEO Bob Olson said in a statement. "Discretionary purchases have declined in the United States as the country is faced with unstable fuel prices, consumer confidence at 16-year lows and a tighter credit environment."

Olson also noted that the industry has seen a decrease in motor home sale sof more than 26% for the first four months of this year and a stead decline of more than 30% in both March and April, which are typically stronger months for recreational vehicles. To help combat the declines, the company plane on closing its Charles City factor and restructure itself.

Many investors should have seen this coming with gas prices skyrocketing higher and recreational spending in general on the decline. However, shares in the company still dropped sharply by 5.69%. The stock is already down some 30% so far this year as many expect things to get far worse before they get any better.
