We used the Coleman Dual Fuel for a week on the trail. Its a bit larger than some folks would want but wasn't an issue with our Zega Pro Panniers. Worked like a charm and had good temperature regulation. I left with a full tank in the stove and a gas bottle on the Panniers with unleaded and it lasted a week.
We released the presure when done cooking so we were'nt riding with a pressurized tank. We were concerned that if the fuel regulation leveler twisted open in the panniers it could fill the box with gas fumes. That could be a potential unsafe situation. That could happen with any stove but with a level action vs a turn nob its probably more likely with the lever.
Overall we loved the stove and think its a better all around solution for ADV riding than the canister stoves because of the versatility of using unleaded fuel the price point at 50 bucks and the good temp regulation that you don't get on the higher end stoves like the Jet Boil. Folks love the Jet Boil but i suspect they aren't doing a bunch of actual cooking. Make sure you tighten the cap before storeing in your panniers so you don't leak gas on your stuff.
