We just purchased a 2012 CR 40FKSS. The brochure states that this has two gray tanks,, but I can only find a single gray drain gate valve. The tank gauge shows two tanks also. The tech who did the delivery with us said that there must only be 1 tank, instead of the 2.

When we were looking on the delaer's lot, a resort model with same floor plan had two gray gate valves.

We would appreciate some assistance to what is actually installed on our unit.

Thanks
