Joel,
I could not read the lettering in most cases either and was reading between the lines in many cases, not sure if I have it right. It would appear that all paths are fused except the Big Boy input.
In my opinion Monaco should have fused the house battery lead after the initial battery switch to protect the panel that has the Big Boy. The fact that the Big Boy is a mechanical device which could short leaves this configuration unprotected from something melting down. Much easier to replace a fuse than a custom buss or something worse. If it were mine I would probaby add one. Hopefully Mel has electrons flowing again...maybe we will hear from him soon.
Later Ed
