Getting a private base is one of the things i strongly suggest to all players. Start an alt as a "Base Commander", give him 10k caps, and use him to go buy a DIY base. Lead the worker to some zone very close to where new alts begin on the map, 1 zone just west of Hub. Site it, and build it. Park that base commander there and leave him there at the terminal forever. He can even remain Level 1.
Now every time you start a new alt, run that new alt to the worldmap and log into your base commander. Touch terminal and add your new alt's name as a non-member record. Set the Status of the new alt's name to "Friend". And set Friends to "Allow access".
Log back into your new alt and you now see the base dot on your worldmap. Go there and immediately pick up a stack of gear, Skill Books, drugs, etc - whatever you put there for your new alt to hit the ground running. This is the fastest way to get all your additional alts going.
Oh...and of course this base is where you stack piles of tent maps. So your new alt goes there, reads all the maps, and instantly sees your whole network of parking places.
Don't share this one. This is the capstone of your own personal security pyramid. Next level down is a base you and closest friends share, but keep this one to yourself. The 3rd level down is some crazy faction of people you just met. There will be thefts at the 3rd level. Cars will be stolen. Drugs will be missing. Who took my combat armor? I put ammo here - where is it. Ahhhh...but no worries since you have an upper level to your security. All your best stuff is safe.
