Hey all, I thought I was a member a long time ago but I couldn't remember my username or even what email I was registered to, so I just made a new account. Anywho, I've had a 2004 Rockwood 2518G for about 10 years or so. I've always used shore plug in power and never even had a battery hooked up to my pup. We now want to camp at a place that is a no-reservation place with some sites with power and some without. I charged up a deep cycle RV/marine battery I got awhile back, tested that its charged to about 12.8 volts, hooked it up to the wires on the tongue. No power to anything, no lights. I can't seem to find a battery shutoff switch in the camper at all. Fuses in the box look fine. Obvious dummie question, but what am I missing?
