I'd agree about the disclosure . . . .
IF this is really a Mobile Home:

From her picture, I think this has to be one of the best disguised Mobiles I've ever seen, and I'd have no idea that it is a Mobile Home
EXCEPT that the OP told us that it's a Mobile Home.
If the advertising for the place includes those words, I'd strike them and let any prospective Buyer make his own discovery.
I'll ask again . . . . What records are there to indicate that it's a Mobile Home? Is there a UCC tag on it somewhere? Is there a mandatory construction decal in one of the closets with the unit's specifications, Manufacturer, Model ID and Serial Number? Did it arrive on it's own chassis and axle or was it transported on a flat-bed? Did the original Building Permit refer to it as being a Mobile Home being placed on the Site?
If there had been an Appraisal of the property at the time the OP bought it, the Appraiser would have noted the nature of the construction. In 20 years, only once have I had an Appraiser be fooled into reporting a Mobile Home as stick built. The information is there.
If the term
Mobile Home doesn't apply, then DON'T USE IT !
Maybe it's really a
Modular ?
