My goal was to come up with a way to mount my Scepter Military Fuel Cans (MFC) and Military Water Cans (MWC) securely into the bed of my Gladiator. I did not want to drill any holes into the bed so I used the Mopar Trail Rails and the mostly unused space above the wheel wells. Most of the pieces were purchased from Amazon and links are below. The rest of the hardware I picked up from Ace Hardware. These mounts fit both the MFC and MWC perfectly with enough room for the plastic to expand in the heat like they tend to do. I chose to mount the MFC's in the bed like this on the drivers side, to enable the use of a electric fuel transfer pump directly into the Gladiators fuel cap. I have one MWC mounted on the passenger side.

I started with these Racewell Mounts. I drilled out the two upper holes to fit the 3/8" mounting screws. I replaced the lower two screws that attach the side braces to the top and bottom ring with longer screws to allow installation of the rubber feet. The thread pitch of the welded in nuts for the side braces is M6-1.0. If using one rubber bumper, I used a 20mm screw and for the two bumpers (more about that below) I used a 45mm screw. I placed a fender washer on each side of the rubber bumper that made contact with the trail rail or fuel can mount to help spread out the load or else the rubber was being too easily deformed when the screws were tightened down to the Trail Rails. Additionally I used four extra fender washers as spacers between the double rubber feet for the rear mount.

T Slot Nuts for the Mopar Trail Rail. I recommend putting something behind them, like 90 degree needle nose pliers or a large Allen key, when your first tightening the screws because the nuts tend to fall back at an angle into the Trail Rail when they're loose.

These 3/8-16 x 1-1/2" Button Head Socket Cap Screws to attach the mount to the T Slot nuts.

These Rubber Feet. I used these for three purposes. One was to space the fuel can mount away from the Trail Rail enough to clear the mounts for my Alu-Cab and second to allow the fuel can mount to be attached as far forward in the bed as possible. If you look closely in the one picture above, the bed side curves inward and these rubber bumpers allowed me to mount the fuel cans almost 2 inches further forward. At first I didn't attach any rubber feet to the bottom, but I found out that the fuel can mount flexed quiet a bit when a full fuel can was inserted. I didn't believe it would survive long. The lower rubber feet help counteract the weight pushing down and push into the bed side. If your going to install them like I did in the first picture you will need four feet for the front fuel can mount and five for the rear. This is due to the bed side curving out past the wheel well as you can see in the one picture. For the upper two mounts I drilled out the holes in the rubber feet to 3/8" to fit the mounting screws going into the Trail Rail.

very cool execution. I did something very similar because i wanted to utilize the space above the wheel well. The can holders didn't hold up to the abuse. I jumped the truck and watched my full cans go flying. I now just have them rachet strapped to the bed and they don't budge at all. which sucks cus i really wanted to use the above wheel well space.

Yeah I’ve been trying to figure out ways to strap down gas and water cans while off roading.

This might be the cheapest option to try although I may also combine both this option and the option from @jn2275.

Thank you both!!

this one is cheap and pretty bulletproof, not a good utilization of space tho imo.

I used to carry my water cans in this space bc all other available space was used by camping chairs, RTT annex, etc.

Since I’m converting my utility trailer to a camping trailer but still wanting to carry extra fuel and water, this’ll work nicely.

I think the weak link in my current design will be if the bottom of the rack can rock inward, it may stress the upper attachment. I'm doing a four week trip in March, including a week on the Mojave Road Trail and my bed will be pretty filled with totes and gear so I'm thinking that will help limit some of that movement.

I'll report back how they hold up.

You should be fine, mine held on for about 2 months. I could see em warping and i should've preemptively sorted it. then i decided a 40mph 2ft jump would be sick. Thats why my cans look so beat up. they went flying, thank god they didn't hit anybody or burst.
