9AD is a great place for people who dont mind walking
Theres a nice opening in the mountains right on the edge of the map you can build a HUGE base and it wont be discovered unless somebody travels to the complete edge of the map.
Just follow the right side of the ocean outside of small rad, towards hacker. Stick to the coast keep moving until the trees disappear. Look to your left youll c a tiny path going into the mountains, up that path is the unknown safe haven.
To get back to civilization follow the ocean coast. If you ever get lost in Hacker or Wasteland just find the Ocean. Half way between your base you can branch off and get some resources in wasteland, it’s a slow process but it is how you can survive on huge populated servers.
12 T is also very good for people who want to be close to small rad, build a 3x3x4 cube with individual walls and keep all your stuff in the middle rooms of each floor. 4 C4min to get inside your base and it’s cheap to build, the higher you go the safer you are. The alternative to this is to make a maze with a few entrances and exits (for home defense) and require somebody to go from each room to get to your staircase, so they have to get through 6 rooms if they dont know where your staircase is.

It’s not the perfect base but it is very ideal it won’t take you a lot of resources to get your first floor done, just make sure you have metal doors leading to each room. Think of the movie Cube, place spiked walls around your staircase and all around the outside, you can glitch them in between walls too. Raiders will normally stay away from the tedious required to get in, even if they blow a few walls they will lose interest unless they have a lot of resources. If you build it high enough you can even place all your gear on one floor and let the raiders try to figure out which center room has all the loot in.
