Any chance you bumped the rear engine compartment remote start button?  

@Bill R  Ivan'door was made by PTL, I believe.  Ours, monaco made in-house. I'm not sure what structural differences there are.   The PTL came with weep holes.  Easy enough to add to ours, however.

Finally got the project behind me.  I've never liked reaching across the toilet room, bending down to turn on the lights.   I wanted to get the switches closer to the doorway.
My toilet room is quite small.  There is just no room to move the switch unless you put in on the wall, but it's just too close to the sink for my comfort.  Water splashing on the key pad was a big concern.   Only way to get it closer to door was to put it up higher on wall, which is fine by me.  Since Monaco put in wall blocking (similar to fire stops in stick built house), mainly to attach back splashes to wall, it took a little creativity to get the new wires to location I wanted  Had to dismantle interior upper cabinet to install the new wire runs as I didn't want anything visible.   Took about 8 hours over 3 days to get everything finished, but happy with results.  Wish I took more pictures.

Chris is right,
My Windsor (similar to the Camelot back in 2006) came from the factory with a 12ga wire run for the sanicon.  That can't handle the new 600 model.  The CB is in the curb side, rear run bay---see picture.   I'm waiting for my sanicon to give up, and then I'm going to replace it, but I'll have to pull a new #10 wire with a new fuse.  #8 is needed if it's a long run.
 

There are 2 fixtures on the ceiling in that closet, with integrated sliding  switches.  She had left them both on with the closet doors closed.   We figured they were on for about 6 or 7 hours.   The light fixture frames are plastic but the housing directly behind the bulb is metal.   When monaco  installed the fixtures using screws, they tightened them on the ceiling  and the soft ceiling material molded around the fixture.  I think from the fixture pressing on the ceiling, it 'pillowed' and came in contact with the metal back plate.   With the extended time the lights were on, the ceiling material couldn't handle that heat.  If you don't have LED bulbs in there, I'd suggest considering it.  Like I mentioned, I changed the basement bulbs to LED, but I just flat didn't  think about the  closet bulbs.
She never did like to have to reach past her dresses to get to the switch up there on the ceiling.  I removed both the lights and ran a LED light strip about 3' long above the sliding doors and then mounted a separate switch.     Much better light and more convenient now.
