Going to get a rear bumper with spare tire carrier and have the option to add fold down table, jerry can holder, hi lift mount, etc.

I’ve never went on a trip (yet) where I couldn’t find a gas station to top off either before starting the trail or after. From an aesthetic standpoint, a dual jerry can holder does look great with the tire carrier. Realistically, if I had one, one would be used for water and the other for fuel. For those that have it, do you leave the cans on the bumper full time? Do you remove them? Keep them on bumper, but empty?

How often do you go off roading?

If you plan to store empty fuel containers on your truck, make sure they are totally empty, dry, no liquid fuel, no fuel vapor.

i run a dual jerry can holder. sometimes i run 2 water cans, or 1 gas/1 water. Having water for washing dishes, shower, drinking, etc makes life easier. Can also put in USB powered water pumps. Its nice not to have the dirty cans in the vehicle.

Around town/daily, i keep my carrier empty, or if you want you can take it off completely.

There are a couple of guys in my neighborhood who keep their trucks fully loaded all the time. I think they live in apartments and wouldn’t have any place to store their gear if they took it off their trucks.

I like the folding table and hilift mount. I took my dual jerry can holder off shortly after purchase and it has collected dust on my garage shelf for the past 7 years.

When you load hundreds of pounds that far rear of your rear axle, you will really start to feel it and likely try to keep as much weight between the axles as you can.

Which bumper are you going with? I am looking at getting one next year and will keep empty cans on mine until needed. Not for the looks but for preparedness as my 4Runner is a 'get the h3ll out of dodge' build. Still have much to do.

Plan on getting the Nguyen Works because it’s the only one I’ve found so far that allows the spare tire to sit closest to the hatch. All the other ones stick out so far.

THIS. I do the same.

Most people that want to carry extra gas go with the RotoPax (Rotopax on roof?). RotoPax is very common with the ATV crowd; I have several of them for my ATV, but I mount the extra ones on my ATV trailer so I don't need to mount them on the 4Runner.

No experience with my 5th Gen but took a trip across the Mojave Desert (Old Mojave Road) in my FJ40 and used my jerry can. Also, convenient in the FJ when hunting hogs "out in the sticks" so as to not pay "out in the sticks" prices.

You can also put water cans in the holders. I have run a few trips where it was good to have extra fuel and I had to carry it in the truck on one trip. A friend carried it in his pickup on the other. It would not have ended the trip not having them but it kept me out of the towns longer and one time from paying a $5/gal premium for gas inside Death Valley. I don't have my bumper/holder yet but I'm planning to have 4 cans. I'll have 2 water and 2 fuel that I can mix and match as the trip needs. I have heard that unless you are trying to prep for a fuel tank rupture, it is good to keep moving the fuel to the onboard tank whenever you can as it keeps the weight lower.

We just went to Borrego. Fuel in san diego was $5.25. Fuel in borrego was $7.50-8.00. Having both cans and a full tank meant that i didnt need to fill up on more expensive gas even after 4 days in the boonies of Anza-borrego. I drained one can into the tank to top off and on the way home we were close to E on the main tank with one full can in reserve.


Also, be mindful: in backcountry area’s sometimes rural gas stations don’t have gas, so being able to extend your range 75 miles (15mpg’s x 5 gallons) might be a good safety measure.

On-road, I usually just leave one can mostly full on my carrier for around town use. I either unload the 2nd or leave it in there empty.

For most off-road travel in the continental US spare fuel is probably not necessary if you plan things properly. The only time I’ve actually had to tap into auxiliary fuel was when I was crossing a really remote part of the Baja peninsula and burned more fuel than I was planning to because of getting stuck in heavy mud. However, having 5 gallons as a buffer for more remote trips is a great piece of mind in my opinion. It has also come in handy helping others, either in our convoy or a random stranger in dire straits.

Leave the Rotopax for Instagram. If you are really using them for fuel storage you will soon find out how terrible of a solution they really are. You really can’t beat the tried and true Sceptre cans. I usually carry one can of fuel and a can of water with a powered pump on my rear bumper swing out for those types of endeavors. I have additional water Sceptre cans stored inside for trips that are longer than a week. Works great for what I do

Late to this thread, but agree with the above post. 99% of people offroading or "overlanding" with fuel cans either don't need them and want the look or have somehow convinced themselves they need them. I've only needed to carry one once, and that was a trip down to the Dollhouse in the Maze section of Canyonlands. 110+ miles one way in, all on dirt from the nearest gas and then a couple of days of driving around and then the same distance back out, a good amount of it in 4LO. 5 extra gallons was just enough to get back. Unless you're spur of the moment leaving for something like this while in the middle of around town errands you don't need to carry around fuel cans all the time. And on the trip I mentioned, I filled mine up as we left civilization, put it on the roof rack and used it as soon as I had room in the tank. That way I got the heavy fuel down low as soon as I could.

I laugh when I see people going to Big Bend NP with extra gas (there's multiple gas stations in the park) or Padre Island (island is only 60 miles long and gas is available right outside the park), but I suspect they're new to offroading or camping and see people with all the overland farkle on Instagram and think they need 10 extra gallons of gas to leave pavement.

Perhaps something to consider for those of us who want to store gas longer term for a bug out, either on their vehicle or in the garage or shed: a distinction should be made between carrying extra fuel and storing it. Rotopax is made of polyethylene which is gas permeable, and after a while fuel stored in polyethylene will lose some its oomph. (And stored too long it turns to varnish!) So if you store fuel in Rotopax containers, rotate it frequently. Maybe 3 or 4 times a year.

I prefer steel NATO style cans myself. But those Rotopax containers are sure easier to mount to the vehicle.
