Thats a pretty rare bird. 30' slide out should really hold its value. Did it say on the tag what it weighed? Make them an offer all they can do is say no.. or yes.
.. or make you a counter offer to which you can think about. To this point you haven't been in much risk of buying a trailer except at low offer that you set and you now know at minimum what they really want out of it.
Have heard the company has no interest in building future slide outs. Which boads for the future value of this trailer. Sort of like having the room of the old 34s without the length maneuverability issues. Plus they are kind of novel everybody wants to come over and check it out.
