I think it's 28 gallons. I would rather do this instead of the Jerry can swing away. If needed, I can stick Jerry cans on my roof, so the long-range fuel tank is a lot more practical; however, adds even more weight to my already VERY heavy LR4. Still, right now I can only go about 240-250 miles on a fill up, would love to expand that range!!!
The rear jerry can swing out is actually still a great place for 5gallons of water though. I don't find it a problem to open it whenever accessing cargo area.
28 (US gallons) sounds correct but I had also though it was 100L which is no where near 28 gallons. From filling, 28 is also more correct for mine anyway. Near empty, in the yellow but not past "0" miles range left, I've put in 51 gallons a number of times. However.... recently I had the pleasure of miscalculating the distance to my favorite fuel station and was short by about a mile... This gave me the opportunity to see just how much could go into the dual tank system. There must be a couple air pockets depending on the ground slope because rocking the vehicle a few times after it appears to be full allows another gallon or so to get in, along with a little patience for the settling that occurs.
53 gallons that time! No joke.
On highway trips, with posted speed limits at 70 mph, I average 19 mpg so 1000 miles is a common goal. Makes it a lot easier to only use "pure gas" (ethanol free) which helps net the mpg by roughly +10% over ethanol blends.
