1963 Camper

Recently acquired this trailer and am trying to find out what model it is. The title says 1963 BOMG. BOMG is listed under Maker but there is nothing listed under Model. The trailer is 15 ft. long. Can anyone help me identify it? I think the only original part of the interior is the stove and hood. Maybe the furnace. It's in rough shape & I'd like to restore it to new condition but need to know what it looked like when new.
