I set up at the Rosewood Northeast gas station and slowly expanded it.
Since I was using a trailers mod, and random zeds kept wandering while I was unloading, I made an enclosed cargo port / maintenance garage that can fit a box trailer.
I'm using the parking lot for scavenged vehicles, got independent generators for sections of the base, crop and animal areas as well as hardware, materials, weapons, books, food and resource storages. I've also looted some conveniences like industrial ovens and fridges, washer and drier, and a bunch of farm animals.
Got preset supply bags (tools, food, medical) on the vehicles I use the most (a small one for recon runs and the day cab for looting and fighting).
Currently working on an off on expanding the base up and moving the living area from the small house on the 2nd story of the original gas station building to another floor on the garage.
