Glad you didn't cause any serious damage Radio. I can see how that could happen though. I know someone who accidently drilled into the top of his "black tank" attempting to snake some wiring. He eventually got it sealed back.
I run my mini-8 coax out at each stop. It's become a routine for my wife and I. We slip it out one of the slideouts, at the floor. Then put the slide totally out. It seals well in the rubber seal. I have a quick disconnect on the roof ladder for the antenna with a SO-239 on the base of it. It's been working well for us so far and I don't have to drill.
We'll be home Monday after having been on the road since June 14th (our longest trip out). I'll try to get our travel log caught up to post soon with photos. We've had a nice time. Currently located at
Ho Hum RV Park, near Carrabelle, FL.
