Campfire ×1 View crafting method here

1. Set aside Wood ×3.
2. Open your backpack, go to “Craft”, and find the Campfire recipe.
3. After crafting, check that you got a Campfire ×1 in your bag, and keep Wood ×10 in reserve.

Use the in-game "Craft/Confirm" button, then check your bag count when done.

Put away the Campfire and return to the material prep step ↑

Check blueprints at the Mainframe; Starport first, then RV

1. Interact with the Mainframe to view the blueprint.
2. Print and place the Starport capsule in quest order.
3. Print the Office RV capsule, place it, and build the RV.

Complete the printing and placing as prompted in-game; when submitting materials, follow the prompts in your Bag and the Mainframe interface.

Confirm Marvin's settlement

Check whether the quest "Print and build the RV Marvin asked for" is complete. Just getting the capsule doesn't count.

Completion check: Marvin moves into the RV

Afterward, you can cook or rest inside the RV.
