I drive a Nissan Hardbody, its the same as a Navara but has some small differances, like the engine is the 3 litre as used in there patrols, 150 bhp as the 2.5 litre is 133 bhp and the rear axle is a little differant. Around town i get 385 - 410 miles on a full tank which is 23-25 mpg , on a run driving like a dear old lady it has done 33-35 mpg and thats on BFG Muds 245-75-16 oh yes and its deisel, never had or used a L 200, hope this helps, ooh its on a 53 plate .
