The receiver has a 50ohm Pl259 coax connector, as well as a binding

The RV itself is a damned good Faraday cage. Aluminum siding, aluminum
window frames and screen. Even the local stations fade to zip when
the door is closed. I have to leave the cell phone near a window to
work. So the antenna has to be external. Shrug.


Others have answered the antenna part. As for the connection, you want
good-quality coaxial cable, with the shield terminated well at the receiver
and at the place in the RV's wall where it passes through. This effectively
places the entire receiver "outside" the RV, as a shield wall completely
surrounds the receiver (you hope) and is then carried out through the shield
of the cable. This is how it is done on aircraft, which are also pretty
horrible
EMC environments inside the fuselage. You may have to put a line filter
on the power plug to the receiver to keep computer hash from sneaking in
on the power cord.
