Thanks to all. Here is what happened. First, I made sure the battery cables were secured so they couldn't short out. Then, I connected the shore cable and everything worked - 110V and 12V systems. However, just as Mudchief said, without the battery, everything worked much slower on the slides - almost having the lights dim out. I just needed to put the slides out and back in - not something I wanted to drag batteries back out for again. So, now I know that on the 3400 everything works except for the slides run much slower.
