Winnebago will supply manuals, or the forums are a good place for older models.

This question is hard to answer definitively because Winnebago make the body, but they build on an engine and chassis from one of the big makers. The information you require is based on the engine not the body maker.

But the other thing is that you are subscribing to the 'let's try replacing this' method of vehicle repair. It doesn't work and it is expensive. Your problems can be diagnosed in 30 minutes by a mobile auto electrician with a $5 grand scan tool computer.

repair water leak first then you can order replacement panels

The cover is often held in place with screws that might be covered by the carpet nap. Carefully search for the fastenings. You could also check at the Winnebago website for the PDF owner's manual for your RV or contact Customer service.

More then likely you will have to pull it out and they are a pain

I have attempted, but failed to decode this...

All I can suggest is contacting Winnebago directly:
Contact Winnebago Industries Call Mail or Visit Winnebago

The lights run off of 12V DC and use your RV's batteries to run when not plugged in. When plugged in it uses the AC and converts it to DC and runs the lights.

Please check your battery disconnect switch. It's most likely off. In my Winne there is a battery disconnect switch which disconnects the two batteries near the door. Lights wont work when unplugged and the switch is off. Lights works when plugged in or unplugged and switched on.

Is the coach already equipped with a generator and you are changing over to LP? If this is the case, usually you can contact the generator mfg to find a direct replacement for the old generator. You will need to cap the supply gas line for the old generator. You will then need to install an LP supply line. This should be done by a certified technician who knows where to secure the line and what size regulator to install. Ensure the generator is properly mounted, exhaust properly installed and routed to prevent carbon monoxide from entering the coach, power load lines are properly connected to the transfer switch (if equipped) and the control harness is properly installed.
