My grandfather came to me asking to help him price his 1979 31ft Sovereign
Land Yacht (aside from the ever mentioned "what someone is willing to pay"). I've done some research and attempted to find an accurate price range, but am not confident so far.
His Airstream is largely all original (refrigerator, microwave, upholstery, windows, etc). The tires and batteries have been replaced within the last few years (original axle). Hopefully the attached pictures will help give an idea of the current state of the trailer (it is not in sale condition as he's not sure what he wants to do yet and also has a trip planned in August). There are several items that could/should be repaired, but that topic is yet to be concluded.
I apologize if I did not include all pertinent information, this is quite a bit outside my area of expertise. Please feel free to ask any questions that you need and thank you for the help!
