I was just wondering if any of you guys kept more than just a few cans of gas onboard like using a 15gallon tank bolted to the floor or a toolbox? Im looking at the 15 gallon from Nothern Tool and was thinking I would mount it to the top of my toolbox inside my trailer. Anybody have any opinions on these things, I think it might save time by only going to the gas station once a week instead of several times
