Winnebago (NYSE:WGO), whose name is just about synonymous with the recreational vehicle (RV), said Wednesday that its net income grew 11%, blowing past analyst expectations and sending stocks in the entire space on a road trip north.

First-quarter earnings, up 11% to $1.01 per share, ran roughshod over expectations for $0.87 per share, with net income rising 11%. In keeping with signs that consumer spending remains healthy, coupled with low interest rates, the company affirmed that there's strong demand for its newest models, citing an order backlog up 42% over last year.

This was big news, seeing how Coachmen (NYSE:COA) flattened some tires Tuesday, warningof a shortage in parts for appliances on its motor homes. Many of the major names in the space -- including Winnebago and rivals Thor Industries (NYSE:THO), Fleetwood Enterprises (NYSE:FLE), and Monaco Coach (NYSE:MNC) -- sold off on worries that Coachmen's was an industry-wide concern.

Winnebago's promising news lifted the other names in the industry Wednesday. Its stock hit a new 52-week high of $67.70 during trading, closing the day at $65.23, while rival Coachmen ended $1.25 higher at $17.14, despite no change to the situation that had sent its stock south in the first place.

Analysts seem to think that the parts supply problem may be worse for Coachmen than other names in RVs. Still, shareholders would be wise to remember that this threat is on the map.
