You should be able to run the line into the trailer through the "hole in the bottom of the convenience center" where the water hose and the electric cable enter the trailer. The back of the convenience center should be accessible from inside the forward storage compartment by removing a panel. Once you have access to the back of the convenience center, just drill a hole, install the plug and then route the phone line to where you want it located (through the bowels of your RV basement) and into the inside of your RV. Then, reinstall the panel, route your incoming line from the campground pole through the entry hole in the bottom of the convenience panel along with your water hose and electric cable and you're "set to connect" LOL

Good Luck
