I too carry extra fuel - sometimes two Jerry cans... I learned real quick back in my working days when driving a JEEP J-series WORK TRUCK that got around 8-10 MPG and only had a 10 gallon gas tank. The closest town with fuel was over 80 miles away going across the back roads of AZ and NM.
I am 'NOT' in favor however to carry them on the rear of a vehicle. This is an instant explosion when you get rear-ended...
I carry mine either on the front deck of my OFF-RoAD POPUP camper or in the back of my truck bed.
This is only one of many PLAN Bs to try to cover all you need to have available for emergencies. It is a never ending task to always be covered. seems like every trip comes up with another 'must have item' to keep one afloat...
This really comes into play when one really camps more off the power grid back in the woods somewhere next to a creek camp site.
My style of camping includes running my 2KW generator every morning for three hours to re-charge my battery bank. Always want to have gasoline for that. I also carry a hand squeeze pump hose to stick down the truck fuel tank to siphon gas if needed. These were called "OKLAHOMA CREDIT CARD" back in the Jeep Days...
