Strong demand for recreational vehicles pumped up Winnebago Industries' (WGO) Q3 earnings by 55.6% to 42 cents per share, topping views. Revenue rose 13.5% to $247.7 mil but missed views for $248.6 mil, as average motor-home selling prices dropped 4.1%. Factors including higher unit sales and gross margin improvement contributed to earnings growth, the company said. Rival Thor Industries (THO) missed Q3 views on both counts due to production capacity challenges. Winnebago shares rose 0.2% to 23.85. Thor fell 1.5% to 56.29.
