Tamiya truck questions

[Terry]

I am getting close to pulling the trigger on my first Tamiya truck but have a few questions first.
I saw on a site that when the MFU is installed the control panel is visible, is there a way to hide it?

It looks like a cord is connected from the trailer to the cab, is this to power the lights to the trailer? If so, is there another way to power the lights so you don't have to use the wire?

Are the trailer legs operable by the transmitter?

What I'm getting at here is I am wanting to know if you can operate everything from the transmitter and connect and disconnet the trailer without having to connect or disconnect anything by hand.
