Welcome dkeel72@comcast.net to the forum. Could you please post the 5th you are towing. Somebody likely has the same unit and can help you better, as for the rest of us it would just be a guess. On my 242RESL I have a door under the furnace that houses the breakers and fuses. I have seen them in closets, in the stairs and seating benches as well as in outside cabinets. Enjoy your times out in the great outdoors.

I'd probably start by looking near the floor on either side of the refrigerator. Lots of information and manuals over here: Customer Service Dutchmen RV
