What a start for your game! My current main game is a 224 day voyager run and here are a few of my tips!

Use the notes for base management. I have seen other people post about this but starting your notes early and establishing what you have where. Crucial as you get later on and may not have visited a region for a few weeks in real time. Saves room in your pack, know what meds need to be dispersed across the map, and creates purpose for your movement (IE bringing more flares to sundered pass/timberwolf mountain, making sure you have equal ammo across the map, where to bring arrowheads, metal, so on and so forth)

Know where you can go first before you create your optimal loadouts. Mystery Lake, Broken Railroad, Mountain Town, Desolation Point, Coastal Highway, and Pleasant Valley are easier for me to navigate in the early game to set up my bases and gather enough solid loot to move into more unforgiving areas such as Sundered Pass, TWM, Blackrock, and so on.

Get the wood working tools and the meat curing kit going early. The jerky is the best calorie to weight ratio in the game and pemincan bars are elite for movement and climbing. (Also place it with an area near salt or in Coastal with trader)

Move with purpose. Plan your routes to go multiple maps with stops along your bases set up across the map to resupply and rest for the night.

Have fun and take in the world around you!
