congratulations on finishing your TD!
I finished mine just before the eclipse and took it on a 600 mile round trip to view it. every nut that wasn’t a lock nut vibrated loose.
my son just returned from a 2000+ mile trip, and the lock nuts on the machine screws acting as hinge pins on both doors vibrated off. the hinge screws stayed in place. I had noticed when I installed them that the screws were not quite long enough for the lock nuts to get a good bite on. I replaced them with the next longer size. (Home Depot has a wide selection of stainless screws, bolts, nuts, washers, etc at reasonable prices.)
other than that everything held together well.
