I'm a believer in checklists. Kittmaster modified one at this post for delivery of his new Airstream. You could make this a starting point and make your own list.
Others who have vintage trailers may rfecommend particular weak points to check like the ones you've already mentioned.
EDIT: Sometimes the good folks here even offer to check one out if you find one far away and want a quick review before you travel a long distance. Just remember, everything looks better in pictures than in person.
