2000 Winnebago Chieftain XCL fuse box

Can anybody tell me where I can find the Freightliner chassis fuse box containing the rear brake/blinker/flasher fuse. The front works ok. Freightliner, Winnebago, and several forums have said different places and I still can't find it. I am stranded and can't move for fear of being rear ended! Thank you.
