Four wheeling involves a vehicle with capabilities enhanced by modifications to suit the owners preference. One of the more popular modifications involves an external tire mounting rack that includes holders for extra gas or water.
There have been many changes to the standard GI style containers over the years in the name of safety and pollution control. While metal is still primary, plastic is growing in popularity. Personally, I’ll take metal.
As evident by the picture at right, metal has a certain durability. The pictured gas can is full and was mounted on external on a Garvin Industries Wilderness series rack. The metal material survived the weight of a jeep while the holder was bent beyond recognition.
