Is this a solar panel hookup?

Hi all. Last fall I picked up a 1993 Jayco JayHunter 950. The seller didn't know much about it, he bought it then realized he got in way over his head. The camper was exactly what I wanted, and I'm having a blast with it so far. But I don't have any instruction manual and it looks like the someone put some upgrades, etc on it.

On the roof, there are some wires that were run through the fridge roof vent. They appear to travel down inside the wall, where they disappear into the camper wall somewhere near the electrical panel, but its all behind the wall where I can't see it. They seem to be the same wires that come down and hook up to a battery, though obviously somewhere they connect to the electrical panel because I can run lights, etc when I have a battery hooked up.

This is the roof, where they come out of the vent (which yes, I need to replace.. dang tree branch):


Close up of the ends:


The cabinet for the back of the fridge, where these wires run down the fall on the far left side:


And this is where I'm assuming the same wires (or ones connected to them) come out that I have hooked to a marine battery.. the red is grounded to the truck, white and black had the battery hookups (go figure):


I'm GUESSING these are for a solar panel? I would love to just go pick up one of those kits with the controller just so I don't have to worry about running out of power in the middle of camping at a rustic site. That said, I've yet to run out and I generally only camp 2-3 nights at a stretch, but I haven't done much other than run lights and water pump either. It would be nice to feel more confidant that I could run fans, a small TV, etc for a weekend, or know that I could go "up north" and do some really rustic camping for a week or two and know the solar panel will help keep me charged.

My previous camper was an old 70's pop up palomino and I never did mess with hooking up a battery to it, so I'm completely clueless on how/if these things are usually done (for example, my truck is gas, but it has a second battery.. everyone keeps saying I could hook the camper up to that).

Is there a good article on power somewhere?

Thanks!

2 different circuts here-wires going to roof, wires between added battery and splice.
First roof thing- Rather difficult to trace wires virtually but it appears the 2 wires on the roof are connected to a single metal bracket-so unless your poping fuses melting wires they are obviously same polarity. Which I believe is confirmed by other pics. Looking at refer box I assume the red wire (that you say goes to truck ground) is the light colored wire in roof pics, so I assume the black wire is going to battery ground. IF there was another connector on roof could have been for a solar panle-But a single connector/single polarity it is not, you need both pos & neg.
Im tring to guess why, if this is how it was originally wired, someone would go to the effort to wire a bracket to both truck chassis and camper battery ground. The ring terminal on roof causes me to think antenna-The black wire on roof isnt a piece of coax is it? THough bracket doesnt look like it support anything a hazard guess would be for CB.
Other point for a panle large enough to supply usable power would go thru a controller, panel small enough to hook directly to battery would only be a maintainer not supply source of charge. If your thinking solar all Im honestly seeing usable here is somthing to pull new wires down. What why or how this was originally used couldnt say.

Second are the splice connections used for battery hook up. Wow comes to mind.

On edit: unless what appears to be screwed wire connection is actaully a clamp holding wire sheath-ring terminal is from wire it self-which could give dual polarity, wires are not actually hooked up to same bracket (as black is normally used for hot- white ground) Though in your case I would assume no color meanings-test.

That's what my TC looked like on the bottom surfaces after I carried it with my belching 6.2L Diesel Chev.
