The U.S. economy grew slightly faster during the second quarter than the government previously thought.

In a report issued Friday, the Commerce Department said the gross domestic product (GDP) grew at a rate of 5.3%, not 5.2% as it previously estimated.

However, home sales were down sharply in July, when compared with June, the government also reported.

The rapid rate of GDP growth suggests there should continue to be a large number of consumers who could afford to buy RVs, despite higher interest rates and fuel prices.

However, Federal Reserve Chairman Alan Greenspan, in a speech to bankers and economists Friday, said he doubts whether the economy could continue to grow at such rapid rates in the future, without causing inflation.
