Here’s how I incorporated XM into our 2019 Airstream Flying Cloud 19CB.
It comes with a Clarion radio, Model M303 M508, which is XM READY.
It does not come with a factory installed XM antenna, nor is one offered, and I am loathe to drill any holes into the trailer. PARTS (Prices are delivered)

Open the bulkhead compartment where the DVD player lives. Ease out the DVD player and disconnect the cables. It’s velcroed in place. Remove the 4 screws on the lower left hand edge of the cover that houses the DVD player. Don't try to remove just the 2 screws that look like they secure the “mouse hole” access. They don’t. That little half-moon piece is actually secured to the DVD shelf from the inside. Once all 4 screws are out, the DVD housing can be removed. It takes a little fussing to angle it out and then get it back in. Perhaps shoot a brief video to remind yourself how you did it. Could save some reinstallation grief later.
You’ll now have access to a rat’s nest of cables shoved behind the Clarion radio. One cable is obviously coax. Free it up. It is RG6 and runs to the antenna connection port on the outside of the trailer. Next, pull up the installation diagram for the Clarion radio to see which connector is to be used for the XM module. Free it up. All of the other wiring is best left in the nest.
The XM module comes with an adapter that allows the RG6 to be connected to it. Fish the Clarion cable and the RG6 adapter through the cable hole in the shelf. Connect both to the XM module. I then used 2 strips of sticky-back Velcro to secure the module to the top side of the shelf. Put the loops on the shelf and the hooks on the module. I also used some micro zip ties to dress up the cables hidden under the DVD shelf.
Follow your video to get the shelf back into position and secure with the 4 screws. Next, the DVD Player can be put back. Best if you have some small hands available to get the cables back onto the DVD.
Okay, so that part of the project is done. You can turn on the Clarion, punch up XM and go to channel 0 to get the unit ID. It’s also on the box that it came in. You’ll need that to activate the unit. The antenna.
I ordered a lightweight, compact photographer’s light stand to mount the XM antenna on. The accompanying picture is fairly self-explanatory. I only used the base pole of the stand and stored away the extensions. The extra height was unnecessary and could allow it to be tipped over.
The U-clamps that come with the antenna are too long and the lock nuts that come with it, I suspect, could loosen up over time. As such, I added a ¼-20 nylon lock nut behind each. Used a bolt cutter to trim the remaining threads, and filed down the sharp remnants.
10 feet of RG6 is plenty long enough to allow the antenna to be positioned facing the southern sky, no matter the orientation of the trailer, but not so long as to be a hazard. Also, contrary to the picture, I ended up turning the antenna 180 degrees relative to its original mount on the arm. This allowed for a more compact/streamlined system. Makes it easier to store and less susceptible to being broken off. Connecting the antenna.
The antenna ports on the side of the trailer go 2 places. The female connector on the left goes to the TV. The connector on the right goes to the bulkhead/XM. That’s where you hookup. You can connect the RG6 directly, but sometimes a pain getting the threads to align. Also, to reduce downward pressure on the connector and to make for an easier connection, I added the above mentioned push-on right angle adapter. Storing the antenna.
The system is just a little too large in diameter to fit in a 4” tube such as PVC/ABS. So it won’t fit in the sewer hose storage tube on the underside of the trailer. Nor did I want it bouncing around in there. I could not find a 5” shipping tube. So, what to do?
Found a short, soft-sided rifle case at a local gun shop that was perfect.
Now that you've done all that work, you could either run the wire for the antenna up to and through the front roof vent, or over and up through the fridge vent (if your trailer has a roof fridge vent).
