RV Repair: fuse box, fuse box, chassis

Question
where is the fuse box

Answer
No clue. There are three. One is Chassis. (like one you would find on a 84 truck) They are mounted in different locations depending on floor plans. The others could be (and they won't be together) under the hood and the other inside the coach. Look for a brown door. I am guessing! Good Luck
