So after getting tired of having to swim to the heli crash island and back any time I needed to access my base/get loot I took the matters into my own hands.

And now for the pictures of my base
The base itself w/ farm

Front of the base

Main room

Back area which was added later, explaining the cot/chest locations

Upper level

View of the heli wreck

Those two trees are the only survivors from me building the bridge lol
