Coolant reservoir

Can anyone help me confirm where the coolant reservoir is for a 2004 National RV Tropical T398 is? I am getting a low coolant message but can't confirm which is the reservoir for this. I was told that some manufacturers didn't make one. I also would be happy to confirm which type of coolant to add if I can find the reservoir.

Thanks

    On a 2005 Fleetwood Excursion with a Cat C7, it's located in the very top right corner of radiator opening looking at it from the rear of the MH. It actually sits on top of the corner of the radiator. It has a black rubber flap (that runs the length of the top of the radiator) partially over it, sort of covering it from sight. Mine is made of white plastic.

    Mine recently cracked and caused the low coolant light to come on. If yours is the same, look at if for heat stress cracks and any leaking. It's about $150 for a new tank and a lot easier to change at home than on the road.
