My D1 had 110L of useable fuel in the larger main tank and had twin jerry can holders on the rear bar (so 150L total), and my D3 came fitted with a LR tank holding 190L of useable fuel. While I rarely used the D1's jerry can holders and usually just top up 100L in the D3, there have been a few times when the extra fuel on long trips has come in mighty handy. Think long detours when roads were flooded out and doing lots of driving over several days in Low-Range whilst in the middle of nowhere. I don't think a long range tank is essential, but more of a convenient, 'nice-to-have', if available. Personally, I would like the option of a LR tank on a Grenadier if I was in the market for one.
