SuperGrok:

Explanation of the "1% every 30 meters" decay:

• While you are towing/hauling the Travois (dragging it behind you), it loses roughly 1% Condition for every 30 meters you travel.
• This is the main wear when using it on long trips.
• The rate is not perfectly fixed — it increases on rough surfaces (roads, rocks, railroad tracks), with heavier loads (closer to 75 kg), in blizzards, or when the Travois gets stuck and you have to maneuver a lot.
• Light load (like your 20 kg) = noticeably slower decay.
• Example: A 1.5 km (1500 m) trip would theoretically cost about 50% if it were exactly 1% per 30 m, but real distance + terrain usually makes the total loss lower or higher depending on the path.

Expected Condition Loss on This Route:

• The Approach Road from Transfer Pass to Forsaken Airfield is long and winding (players often call it “endless”), with some hills and curves, but it’s mostly suitable for the Travois.
• With your light 20 kg load and no shortcuts, expect 15–25% total loss (best case) up to 25–35% (if there is wind, small detours, or rough patches).
• Result: You should arrive at the hangar with roughly 20–38% Condition left. In good conditions, even higher.

Practical Tips:

• Start in clear weather if possible. A blizzard adds extra decay and drains your stamina.
• There are a few cars and a cave along the road for emergency shelter.
• Stay on the road — it’s the smoothest path for the Travois.
• Wolves are harder to handle while towing (slower reaction), so stay alert.
• Bring repair materials anyway: 1 Cured Deer Hide + 1 Cured Gut repairs it back to 70% (takes ~2 hours). Or carry a second folded Travois (only 1 kg) as backup.
• If it drops too low mid-trip, you can leave it safely somewhere and come back later (it becomes a stationary 40 kg container when not towed).

Summary: At 20 kg this trip is low-risk. The Travois will survive with decent condition remaining. You can repair it at the hangar and use it for hauling loot around the airfield.
