I carry the gas can outside so that when someone hits me from behind, we will both experience the ball of fire. To the best of my knowledge (now I have opened myself up for abuse) there are not any stock transfer cases made with synchronized gears. This means the truck should be at a standstill when moving the lever from High to Low. This is different than 2H to 4H. For both my Fords and one Toyota I put the truck in neutral and ease the lever between H and L. If it won't go into gear easily, I let my foot off the brake and the small roll will get it there.
Just for more info, the NATO plastic cans that I have actually have indentations on the bottom where the bolts from the can holder sit so that they don't come in contact with the bottom of the can. The holder I use is from Academy and I originally bought them for use with the metal cans.
