I suppose it depends upon your application, meaning where and how you drive. But a side mounted Gerry can is vulnerable in a side tipover, or getting damaged when passing rocks and trees.
It may be primitive, but I use a short piece of 2"x2" square tubing inserted in the receiver hitch, supporting two Blitz cans in the clamp-style holders. The receiver insert sometimes drags on the rocks, but I only use it when I need it, and always top off the tank and stow it in the body of the Jeep after burning 10 gallons on the trail.
