The unit is now in storage, which gives me time to figure this out.  The green/white wires are for lights, indeed.  Im trying to understand the logistics of moving these lines from the hole floor to in the revised dinette bench seating (front L end).  I have no background in electrical, so any detail in what is recommended would be super helpful.

Get a mulimeter if you don't have one already. Confirm what voltage you have between chassis ground and each of the two wires. You can check that at the nearest terminals if you can trace the wires that far or if need be you can strip a very small amount of insulation off so you can just see and access the copper, then tape it up with electrical tape after. For safety use an insulated tool and disconnect 120V before doing any stripping.  

You can turn on the lights or other items you suspect the wires go to and check the voltage again to confirm your suspicions. You can also pull fuses or open circuit breakers one at a time. Its good to have a helper for that. 

Hello Camp town,

It would be helpful to post a picture with it. You need to go to the advanced editor to do that. Look on the icons above the text entry box. There is one that looks like two overlapping squares with an arrow pointing to the top-right corner. That will take you to the advanced editor which has the icon for posting a picture. It works best if you use a program like the GIMP or other graphics program to resize it to 800x600 or at most, 1024x768 before posting to limit the size.

Third, welcome! How long have you had your RPod 178? I have a 179, so I can't help you with the wiring. With the 179, we have the wiring on the ottoman on the other side. I built a frame and covered turned the ottoman into a small compartment where we store documentation, a small whisk broom, some microfiber cloths, and a Thermocell mosquito repeller. Maybe you could do something similar with yours.

I have removed one of the peninsulas on the U-dinette to have more floor space.  Before i can move on i need to understand some wires.  I am seeing a green and a white line, which i think are for Ext lights.  They come straight out of the floor 2 feet off the wall.  I need to move these out of the way. There also seems to be a huge gob of expanding foam on the unit belly - not sure if these are the same thing but look about in the same area.  I m not having luck with pics.
