Thats right Donnelly...keep driving that RV
The RV industry is big in Indiana, and in 2008 it got burned by a combination of high interest rates, a credit crunch, and a spike in gas prices. RVs are expensive purchases often made on credit or from the sale of houses (related to the overall economy), and they devour huge amounts of motor fuels. The economic meltdown hurt the RV industry, and Obama did freakishly well in the counties on the Michigan border in 2008.
An RV is a costly, environmentally-destructive vehicle, but it is also how many Hoosiers make their living -- working to build them.
