simple network hardware question

[BrianR]

I have. Thanks guys. I can find something like this but not for RJ45. Part of me is jonesing to just enlarge that opening and insert a RJ45 plug.

Mitch had a good idea going in through the bottom of the trailer, but that would require cutting through the insulation and vapor/insect barrier and I would prefer to avoid that if I can.

I know enough to choose the correct cable and boxes. I was worried about losing data over such a long cable, which goes outdoors and through several outdoor connections which might get corroded/intermittant from humidity or whatever. Some things are beyond my training.

Thanks for all the input. I will order a waterproof box, go through my wall and pay attention to strain relief and grommets.
