Power still on when key is turned off

[gmasters]

Ok traveled 500 miles in this east coast rain and had a little trouble come up. During the day when we started back to driving from say a hour long nap, the couch wouldn't start.
Some how the battery dead and was drained some how, thought that i might have left lights on but later whe we pulled over to park for the night, I saw that my damn backup camera and level control system was still powered up. I mean the lights and still on. The head lights turn off at the switch as does the rear view camera but it's still got the light showing power is on.
Damn drove in the rain yesterday and it's still raining
I have a short someplace,

Good morning on this rainy morning.
You haven't said what chassis you have but a short is probably right.
The fire wall area at front of coach is going to take in allot of water from wiper action and just driving rain as you travel.
There are plugs there that usually have rubber seals within them as you plug together.
You could have one thats come unloose and is not locked completely.
If you continue to drive in rain the short could cause you more problems if not found.
