Going on a trip with a 410km (255 mile) stretch between gas stations. Hopefully this will do it!
3.7 liter (1 gallon) Rotopax, 7.6 liter (2 gallon) Giant Loop gas bag and a 2 liter (1/2 gallon) Touratech fuel canister in a 5.11 Tactical pouch.
Usually only need the 2 liter filled for emergencies and the Rotopax for more remote areas. The gas bag can be rolled up for all but the long stretches.
If this works, the Fury could do the Dalton or the Dempster if gravel isn't a concern!
Think I'll continue to avoid gravel if possible though.
