I do not know, but Evergreen could have gone out of business by focusing on the quality of construction materials instead of the bling. This unit has a TPO roof which is much better than EPDM. It has fully welded aluminum framed, laminated sidewalls, roof and floors. It has something called, Apollo Chassis System, which who knows what that is, but one good thing is that the term is not found on the Lippert site. Try to find a brochure on the unit if you can. This page has a "download brochure" link on it:

If it passes your inspection and research, it may be a rare opportunity to get a good price on a better than average constructed unit.
You may also want to keep an eye out for any Evergreen Ever-Lite models as these use exterior composites. I used to own a 2012 Ever-Lite fifth wheel, it was all composite and a Dexter frame. I think later models started using some plywood in some spots but the walls are still automotive high gloss gel coat exterior with composite substrate.
