The trailer is a Great Western and was designed by Frederick C. Hoffman, designer of Aero Flite. This is a super rare camper- i believe only 5 are know to exist. You have seen pictures of some of those restored and they are spectacular (see pic of the cover of Vintage Trailer magazine featuring one of the restored ones). More pictures to follow
Key components are present including Murphy bed.
Asking for $50 K but willing to discuss reasonable offers. Can hold on to it until you pick it up. Would recommend putting it on a trailer given age of the unit
