I'm actually going to be using it as a teaching tool. I am a turnpike driver up here in Canada. The company I work for has turned me into an instructor. So once this is done I need to build 2 53ft vans as well as a C-converter and a tandem axle A-converter. It will be easier for me to teach if I have props plus it will get the guys more eager to listen to me if I have stuff like this. But most of all I get to have an excuse to build this stuff.
