Glendale was a Canadian RV manufacturer who went bankrupt in 2011. The Golden Falcon trailer was considered a fairly high end product and a good comfortable trailer with some fairly unique features for its' time. One was the recessed awning into the side of the trailer.
They also came with gel gloss hung fiberglass sides and both front and rear FG end caps.
Here is a link to an advertisement for one that I believe is quite old and not available anymore. It will show you how the exterior and interior was arranged and what the walls etc. looked like. Hope this helps you out a bit. If the rig has not had much water damage, it is probably worth spending some time on - IMO.
