DREW INDUSTRIES REPORTS THIRD QUARTER RESULTS

White Plains, New York – November 1, 2004 – Drew Industries Incorporated (NYSE: DW) today reported that third quarter 2004 net income increased 14 percent on a 55 percent increase in net sales, reflecting market share gains in both Drew’s recreational vehicle products (RV) and manufactured housing products (MH) segments.

Drew, a leading national supplier of RV and MH components, reported net income of $7.5 million, or $.71 per diluted share, on net sales of $149 million in the third quarter ended September 30, 2004, compared with net income of $6.6 million, or $.64 per diluted share, on net sales of $96 million in the same period in 2003. Drew’s 2004 net sales, net income and net income per diluted share were all third-quarter records.

Drew reported that net income did not grow as rapidly as net sales primarily due to continued increases in steel prices which had not yet been fully passed on to its customers. Management estimates that as a result of the unrecovered steel costs, net income for the quarter was reduced by between $.07 and $.14 per diluted share. Additional sales price increases and surcharges to customers have recently been implemented by Drew in an effort to mitigate the effects of these higher costs. The Company also noted that it had incurred start-up costs related to new products of about $350,000 in the current quarter. In addition, 2004 third quarter expenses related to the implementation of Sarbanes-Oxley and stock options increased approximately $500,000 over last year’s third quarter.

Net income for the nine months ended September 30, 2004 reached $21.7 million, or $2.04 per diluted share, compared with net income of $15.2 million, or $1.48 per diluted share, in the same period last year. Recently-acquired Zieman contributed approximately $.05 per share to the 2004 nine-month results, and its operating margins improved over the second quarter. Drew reported that its second quarter and third quarter results are traditionally the strongest in terms of sales and profits due to the seasonality of the industries in which it operates. Net income for the twelve months ended September 30, 2004 was a record $25.9 million, or $2.45 per diluted share.

“Material costs increased further in July and August, and these additional cost increases have just recently been passed on to customers. The impact of these material cost increases overshadowed what was otherwise a strong quarter of sales growth and profitability,” said Leigh J. Abrams, Drew’s President and CEO. “Our management team has done a great job on the operational level to manage rising commodity prices in this difficult economic environment. Steel prices now range from double or triple prior year levels. It’s always difficult to raise prices, but in this situation we’ve had to go back to customers a number of times due to continued steel cost increases. Our customers have been cooperative, but many have also been impacted by higher commodity costs and it has taken longer than expected to fully implement the sales price increases we need. On the positive side, it appears that steel prices may be stable for the balance of 2004.”

Drew said its $53 million increase in net sales this quarter, compared to the third quarter last year, came from a variety of sources. Organic growth from existing operations drove a sales increase of 23 percent, or approximately $22 million from the third quarter last year. The acquisition of Zieman, along with a small acquisition completed late last year, added $17 million in net sales. Price increases to customers, to offset the higher costs of steel and aluminum, aggregated nearly $14 million in the current quarter.

Exhibit 99.1

Drew’s RV segment achieved a 62 percent increase in sales this quarter (47% excluding sales price increases), but only a 4 percent increase in operating profits due largely to the impact of material cost increases which had not yet been fully passed on to customers. The profit margin of the RV segment in the third quarter last year was higher because steel costs had temporarily declined compared to prior periods. Production efficiencies in the current quarter remained high in all major product lines of this segment, and fixed costs are being spread over a much larger sales base.

“We are continuing our stringent control over operating costs while at the same time further developing our management team, systems, and research and development capabilities, all of which are essential to continue our growth,” said Abrams. “Because of our efficiency efforts, we were able to achieve improved profits year-over-year despite our biggest cost – raw materials – increasing drastically. We will continue to remain diligent in managing operations to maximize profits.”

Drew’s MH segment had another strong quarter, with sales increasing 44 percent and far outpacing the industry. Industry sales were down 1 percent for the 2004 third quarter, despite the shipment of about 1,800 homes ordered by the Federal Emergency Management Agency (FEMA) to provide emergency housing to hurricane victims. Year-to-date sales in the MH industry are down 3 percent, while Drew’s MH segment sales have increased 34 percent and operating profit grew 38 percent.

“Drew’s MH segment continues to report outstanding results despite continuing sluggishness in the industry,” said Abrams. “While there is still no clear sign of improvement in the MH industry, repossessions have declined and lenders have been successful at raising the money they need to provide home mortgages. Some industry analysts are projecting significant growth for the industry in 2005. However, we remain cautious about the industry in the near-term. We are confident in the success of our MH segment regardless of whether a rebound occurs and we have a positive long-term outlook for the industry.”

As a result of the rapid growth in sales by both of the Company’s segments, and higher steel costs, Drew has continued to invest heavily in working capital and capital expenditures. “Our inventories peaked in August and have since declined by about $8 million,” said Fred Zinn, Drew’s Chief Financial Officer. “We expect capital improvements to exceed $22 million in 2004, including the addition of several new factories. Despite this, cash flow has been very good since mid-September, helping us to reduce debt. Based on recent trends and current conditions, we expect our total debt to decline by $10 — $15 million by year end, to $60 — $65 million, which will further reduce our leverage.”

“To ensure that we have the ability to take advantage of expansion opportunities that may arise in the future, we are in the process of restructuring our corporate line of credit and adding borrowing capacity,” said Zinn. “We anticipate increasing our line of credit with JP Morgan Chase and KeyBank to $60 million. In addition, we expect the new line of credit to contain an “accordion” feature, which is an understanding that the banks, while not formally committed, are inclined to increase the $60 million line by $30 million upon the Company’s request. In connection with the new agreement, HSBC is expected to join the bank group. In addition, we are negotiating with Prudential Capital Group for a $50 — $60 million “shelf” facility, which is an uncommitted line that the Company would seek to use to finance a significant acquisition, should the opportunity arise”. At October 29, 2004, borrowing under the Company’s current line was approximately $38 million.

Abrams added: “All of our actions are focused on the execution of our long-term plan for growth and profitability based on outstanding management and serving the needs of our customers.”

Recreational Vehicle and Leisure Products Segment

Drew supplies windows, doors, chassis, and slide-out mechanisms and power units, primarily for travel trailers and fifth-wheel RVs. Industry shipments of RVs have continued to grow during 2004, with 2004 RV shipments up 17 percent for the first nine months of 2004. “Long-term demographics for this industry remain strong. While the RV industry association is projecting an 8 percent decline in industry shipments in 2005, we remain confident in our ability to continue to out-perform the industry and grow this business,” said Abrams. Drew’s RV segment far outperformed the industry by achieving a 59 percent increase in sales to a record $263 million for the current nine months. Even excluding price increases and the $16 million of RV sales by newly-acquired Zieman, the RV segment achieved strong growth in all major product lines.

Exhibit 99.1

The operating profit margin of Drew’s RV segment declined to 8.7 percent in the third quarter of 2004 from 11.1 percent in the second quarter and 13.5 percent in the third quarter last year, largely because of continued increases in the cost of steel that were not fully captured through price increases to customers. During the third quarter, the cost of steel and aluminum used by the Company was approximately $16 million higher than it would have been at prior year steel prices, including approximately $11 million for the RV segment alone. While much of this cost increase was previously passed on to customers, sales price increases covering third quarter increases in steel costs have only recently been passed on to customers. As a result, the Company said that third quarter gross profit of the RV segment was reduced by $1.7 to $2.7 million. The impact of higher steel costs was partially offset by a decline in overtime and group insurance costs, which had been higher than typical for the past several quarters.

“Drew’s product innovations continue to yield near-term and future growth opportunities. Drew recently introduced a new line of slide-out systems for motorhomes, which have a market potential of approximately $40 million. We also introduced bath products for RVs. Although sales are still modest, we saw increased sales of these products compared to the prior quarter,” Abrams said. “We have also substantially increased our spending on research and development and quality control in order to improve production efficiencies and speed new product introductions. As a result, we will shortly bring to market several high quality new products such as leveling devices, new axles, and steps for RVs. Product innovation and market expansion have become the core drivers of growth at Drew, and we will continue to make them focal points in the quarters to come.”

Manufactured Housing Products Segment

Drew supplies vinyl and aluminum windows and screens, chassis, chassis parts, and bath and shower units to the MH industry. While hampered by the prolonged industry-wide slump, Drew’s MH products segment has been profitable every quarter since the downturn began in 1999. This segment’s sales and profit momentum from the first half of 2004 continued into the third quarter, as operating profit increased 36 percent over the third quarter last year, to $6.4 million, on a 44 percent increase in net sales. Even excluding sales of $6 million from newly-acquired Zieman and price increases, Drew’s MH segment sales increased about 15 percent, compared to an industry-wide decline of 1 percent.

“Our MH segment continues to pick up market share, and we see additional opportunities to expand our penetration with product line expansions such as new bath products to compete with fiberglass bath products and other products,” Abrams said. “As our content per home grows and we sustain profitability in this down market, we put ourselves in position for significant growth if and when the market begins to improve.”

MH industry production levels are likely to receive a short-term boost in the fourth quarter due to the purchase by FEMA of additional manufactured homes to provide emergency housing for hurricane victims in the southeastern United States.

Other Matters

Mr. Abrams has advised that he is scheduled for cardiac by-pass surgery on November 19, 2004. He expects to be available for consultations shortly after the operation, to resume partial duties in mid-December, and to resume his full responsibilities as CEO and President at the beginning of 2005.
