"Maxcom"......Your coach has a build number, not the VIN, but a number that should be in a couple of places in the coach (6 digits, all numbers). Often there is a tank quantity page and weight info glued to the back of a bedroom or bathroom cabinet. It will have your coach build number. You can also find it in other spots, like near the driver's seat. Once you find this, you can email Monaco with he build number and request the original build sheet, that tank quantity page for the bath and I bet the fuse cover diagram. Just ask, they are good about sending you the info.
