I think I found it for you. I used the search function of the 5th Wheel Forums with the search phrase "inverter wiring." It said there was 110 responses, so I almost panicked. Then I saw a thread that had your username on it at the end.
Here is the link to the thread:

Then I found this link within that forum thread to someone with a last name of Palmer in Milo, FL.
http://www.palmerenergysystems.com/
So, is this the one you were referring to?
