Did you notice the box built over the engine in the RVs? Yeah, why would they make these things without cup holders?
I'm not personally bothered by the noise of the engine in my FE bus. I like to hear what the engine is doing. Listen to the turbo spooling up and stuff. I am, however, very disappointed that there are no cup holders built in. I planned on also building a box that incorporates cup holders and additional cubby pockets similarly to the S&S folks.
