Over time my various player characters have become well-known enough (those still alive and more or less regulars) to have various places they regularly hang out and stash their gear, extra parts, etc. It has been a change form past practice where their ship is generally treated like a garage/mobile home/office.
Most are just some warehouse or cargo container at a starport in a good location owned by someone they know and trust. On those occasions when they have had to go to ground that's where they end up.
But in the current campaign they have now ended up on the losing side of a trade war gone really hot and went looking for a place to lay low and work out a scheme to save their necks and help bail out an important patron.
They picked a Red Zone that used to be the major Naval Depot for the subsector prior to the last war. It was evacuated while the Imperial Marines (IMTU...not OTU) made a valiant last stand to rival all last stands (which players in a prior campaign also participated in as civilians contracted to evac the wounded and base personnel - and posthumously earned Imperial Stars for) in order to buy time for the Main Fleet to arrive and throw back the invasion. The system is now locked up as a hazard to navigation and war memorial all in one.
The system is riddled with ship, asteroid, and planetary debris....but it has a gas giant and uncounted places to hide if you are a good navigator and pilot. The background radiation and junk make it reasonably easy to avoid the gunboat patrols if you have the skills and daring. And all that debris contains useful (and free) ship parts that sometimes even still work.
So the players are paying off the Lt in command of one of the gunboats to look the other way if they get spotted (though they are starting to think he is "spotting" them a little too often lately and might be getting greedy) and have staked out the wreck of a 150kt heavy cruiser as their hideaway. It's mainly been gutted from salvage ops when those were still going on, and they have enough room to park their 200 ton privateer, which then doubles as the power plant to keep the section they fixed up as living quarters running when they are home. They are deep enough inside the wreck that they are well hidden from sensors, especially with the iffy reads you get form sensors in the whole area anyway.
It isn't much, but it'd have to be a pretty determined bad guy to run the gauntlet of gunboat patrols and all the junk in the system to find it. And when they leave or enter the system its sometimes like running The Hunt For Red October if someone other than their "buddy" is patrolling nearby and they have to play hide and seek through the system to find a safe exit. They've even started calling it "Archangel" when I pointed that out and start in with bad Russian accents and lines from the movie now when they play.
I swear, if I hear "One ping only, please." in a bad imitation of Sean Connery one more time I'm blasting them with a spinal gun.
