Ok, I've managed to find the 2 bolts holding the side nearest the cabover, they were to my astonishment, easily accessible and right in front of my eyes on the underbelly of the camper :S
Thanks opnspaces, I removed the fire extinguisher I found a single bolt protruding from the dark! Now a single bolt remains above the generator housing, but below the couch bed frame.
I was trying to leave the upholstery in as good a condition as possible (unsure if that helps upholsterer or not), but ended up cutting through a portion of it to see if I could unbolt from the top of the frame, however the bolt is welded in and looks like I'll either need to remove the generator housing to get to it, or cut the bolt off at the frame and figure out another way to reattach it once finished.
