Motorized RV backlog increased 42.3% to $343.3 million from $241.2 million a year earlier. "Thor's sales for the second quarter were adversely affected by the severe winter weather that has plagued the Midwest this year. In January, our operations in Indiana lost several days of production due to severe cold temperatures and heavy snow," said Bob Martin, Thor President and CEO. "The severe weather affected our ability to receive materials, run production and ship units amid the frigid temperatures and hazardous road conditions. The second quarter sales total also reflects the impact of certain operational moves we've made over the past few months. Ultimately, these factors have resulted in a shift in the timing of deliveries and revenues from the second quarter to later in the year as indicated by our backlog growth. The RV markets remain strong as reflected by the higher traffic and increased sales activity we've seen in the early retail shows," he added. Thor expects to report its second-quarter operating results on March 6, 2014.
