Once I realized the Chinese made "NATO" jerry can I had purchased wouldn't work I began searching for a replacement. The place I found and will strongly recommend is CampingMAXX.com down in Texas. Jerry sold me four USED NATO jerry cans, four new gaskets, and a new filler for $199 shipped. I ordered the cans last Thursday and they arrived today (Monday). As stated the can are used but in very good condition. In fact, I am really pleased with them. I'll be painting at least two of them red before installing them on the trailer.
The Front Runner holder is really a nicely built unit. It holds the two cans very securely, once the latches are properly set. I do have one issue with the build. When installing the latches the Front Runner documentation shows threading the button head bolts from the rear, through the latches, and then installing a nyloc nuts to hold them in place. I have found it is much simpler to run the bolts through the latch first then back through the Front Runner straps. Doing it the way the diagram shows is very difficult because one cannot get a 7mm socket or wrench to grasp the nut.
Here is a pic of the diagram I'm talking about. Reverse the way it shows to install the button head bolt.
The latches have a hole through them for "locking" the latches shut. Great idea! I have found that cloths hanger wire is the perfect size to fit through these holes. I've fashened two wire clips to temporarily hold the latches shut. A better solution will be to pick up a couple cotter pins with the appropriate diameter to do the job. I'll pick a couple up at my local ACE hardware when I'm there to get the red rattle cans for painting the jerry cans appropriately. Remember to bend the hanger versions over a bit to hold them in place.
