12V fuse block location, Pacifica, Freightliner

[JVJ]

Well, I have been looking for the Dog Gone 12V fuse blocks on my Pacifica coach. This is on the Freightliner chassis. Last time out my dash radio worked just fine. Today I went out and couldn't get it to turn on with either the ignition swith power or the power switch to run it from the house batteries. So I begain to look for the 12V fuse blocks to check for a blown fuse. Can't locate that sucker for nothing. I did however find an inline fuse that was not seated properly, which was the culpret on the radio problem. So not the radio does work as it should off of either switch.
However, the day may come when I still need to locate that set of I believe it is three different automotive style fuse block distribution panels, can anyone lead me in the right direction and assist me in pin pointing them.
Thanks
