“Note the plates for the underground cellar was blow out. The plates looks like it was behind the RV.”
This makes some sense. Comm buildings are built to be blast resistant. Trying to blow them up from outside is not an effort in futility, but lots of explosives are required.
The underground cellar is likely the cable entrance where all copper and fiber cables enter the building. This is where you sever the communications.
When the cables are severed, the only comms in/out of the building will be microwave/satellite on the roof.

Could the RV have been used as a visual shield? Park it next to or partially over a grate before opening the grate? Kind of poor security though if grates could just be lifted open.
