simple network hardware question

[BrianR]

OK folks. I am trying to run an ethernet cable from my router in the house all the way (about 75 feet) out to my RV so I can have net access out there for a few devices, namely a Blu-ray DVD player and a computer or two.

I know I need a gigabit switch to put multiple devices out there but my issue is more basic. How do I get the cable into the camper without drilling a hole? Should I McGuyver a receptacle on the camper? Drill a hole and seal it real good and make a pigtail? I refuse to run it through a window and compromise the weather seal. Is there an option I haven't thought of?

Ideas appreciated. I am worried that long runs of cable and breaks in the line for removable connections can lead to line losses and data loss.

Thank you!
