Yes, figuring out what the other owenrs may have doem can be a trick.
Some pointers on the Way Winnebago does their wiring may be a start as they do have some things that are different and special.
One big help is reading the notes on the bottom left of the wiring diagrms as they tell you how to read some of the info stamped on the wires.
On the first list of RV and down at bottom left are links to good info to get started on the way they do some things. The ID list can be a biog help as there are ID labels stamped on smaller wires and then we can go to this list to find where that wire comes from and goes to!
The other link is wiring diagram help and can lead to other small points to help.
But that may not help as much as in other cases if the RV has been changed!
Something like we find at our houses? We may have info on what the builder installed but once the furnace has been changed, we need to go to the company that built that speciifc item to know what it does!
If you now have a xantrex, you will need to go to that builder, etc. for info on what you now have and sometimes you will find that the previous owner may not have done the install in any logical way!
Whether the RV ever had an inverter is always a matter of what the first buyer/seller got from the factory as options! Much like cars, the dealer often chooses different as he finds what sells best in his market.
A quick search on Copilot tells me that unit is only a battery charger, so that may mean that there is NO inverter onboard. If you are wanting to convert the RV for letting batteries provide AC power, you sound like you will need to install an inverter.
My guess might be that a former owner wanted to upgrade the charging profile by getting a newer model converter and did not see need of an inverter for his use.
One of the tricks of the used market in cars,trucks and RV is to go to a lower cost region top buy things cheaper and sell in areas where the more fully equipted items sell better. Folks can easily fall into thinking a specific year and model of RV will have the same options. But the truth is that RV are much more likely to be different than what we find in cars.
Like moving into a different house, first step is figuring out what we have!
Best of luck on the trek!
