Glad to hear you had a good ride, sounds like fun.
Mileage wise, I start getting nervous at 160K, but have nursed it to 180, it took 6.7ltr to fill it back up.
Have just fitted a IMS 12ltr tank, still waiting to see when the light comes on.
I also have a carrier for an extra 4ltrs
Should get me into the mid/high 300k range.
Mavora road is cool, Nevis can alter with conditions, lots of water crossings.
