The hump is the engine cover on the inside of the cab....FR, decided that rather than putting a nice console there for your drinks on the road, phone, change etc.....they did not put anything there and I am wondering if anyone found something elegant to put there store bought or was having something made the way to go?
I suppose the engineers had you in mind when leaving that space blank but at 5'5" and 5'4", inches, my wife and I don't have much of a struggle getting in and out and would like something there for cups, phones CD's etc....still looking though perhaps we will find a carpenter and have something made.
Here is what I have on my 2012 378TS XL version
Below the leveler control panel is a compartment.
Not sure if you can see it clearly in this picture.
I also included my center hump cup holder and storage.
