Just a guess on my part, but Heartland made some FEMA trailers at that time. They did not look like FEMA units, but like classy TTs. I think that Heartland's Trail Runner is the successor to this.
I remember a post from Scott talking about the quality that went into these. If I'm right, and this is a new unit, consider it. Be careful, though as FEMA has been selling a lot of used units. Price looks real good for a TT.
