So with this new camper came an option of "Heated Tank(s)". Now, I know what "heated tank(s)" means, but my question is this: When I was doing the PDI and we came to the switches - the heated tank switch! The salesman tells me that ONLY the black tank is heated when the switch is on. Is this really the case with a factory installed heated tank option?
Assuming for a moment this is true, what sense does that make? If it's going to come with a "heated tank" option, why wouldn't they heat the other tanks? Seems to me the fresh water tank would be more important to keep from freezing than the black water tank full of chemicals.
