Ok. Working in rocket.

Until another monument has a vehicle, i can rename it.

Actually I could keep it as it is, but note that the only monument with a vehicle is the rocket launcher?
I am guessing no other monument has a vehicle?

Hmm, the only "monument" I have is The rocket launcher.

Wait, I think I labeled this one wrong.
I may need to redo it as RocketCam.

I suspect it will only view vehicles related to monuments, and the only monument that has a vehicle is the rocket laucher, the vehicle is the rocket.

Thanks I will test it by launching the rocket and see if it shows blank when the rocket is not on the pad...

It seems not to work. I have several monuments and the screen turns black, as if there were no monuments.
I have tried the rest of your scripts and they work.
