Well mine is also my daily driver which I drive over 40 miles round trip to and from work. I saw somewhere, but cant remember where, a 15 gal. tank and wondered if it could be done.
Along with what Midnightrider said I think this is what he's thinking of.
Doubling your 4WD's travelling range with the Long Ranger fuel tank. You can now replace your existing tank with the convenient Long Ranger, saving precious luggage and passenger space, and providing safer, more economical fuel storage for long trips. You'll minimise inconvenient refuelling stops and buy your fuel at the best prices, thereby recouping the cost of installing a replacement or auxiliary tank.Long Ranger fuel tanks are available either as a replacement of the original unit or as an auxiliary to it. In certain vehicles, both a replacement and an auxiliary can be fitted for those extra long trips in remote areas.
Constructed from 2mm aluminised steel, Long Ranger tanks are Mig welded during manufacture. Baffles are fitted at the time of manufacture, as are fuel pick-up and breather outlets. Fuel expansion capacity is catered for in the design.
