Go to there offsite facility at Gillespie Field which is north of San Diego. Aircraft, engines, etc. not presently on display are kept there. Be sure to drive around the airfield too - a few vintage types if you are lucky to catch them out and when I was there in January 2019 (feels like a century ago pre-pandemic), caught an Erickson Skycrane based there. Lufthansa has some Debonairs there for training as well.Going on vacation in the fall and one of the stops is the SDASM. Anything there I want to make sure not to miss?
