Hey Dan,
I can help you look into this, but I don't have any insight into a wiring schematic on your Holiday Rambler Endeavor.
What I recommend starting with is the wiring at the back of your motorhome. Use a circuit tester like part # PTW2992 to probe the wiring where you can see it while someone else runs through the various functions so you can see if the problem is damaged wiring or simply no power coming through at all. If you find damaged wiring then you'll need to replace it, but if the wiring looks good then we'll need to locate the fuse box and start replacing fuses.
I was able to find an online manual for your 2006 model and it said the chassis fuse panel is located in the front roadside bay, and the house fuse panel is located in the bedroom. You should be able to find all of the fuses for the trailer 7-Way socket in the front roadside bay.
From here you'll want to refer to your owner's manual for replacing the correct fuse. If you don't have a physical copy of it, Holiday Rambler has their manuals available online and you can get a copy of it here - https://www.holidayrambler.com/owners-manuals/
