We have just returned from 5500km trip towing a Kimberley Camper. Our 2006 CRDauto has just clocked up 10,000km. The first 4500km prior to trip average was 11.7L/100km (best 10.5, worst 13.
made of 80% 110km/h freeweay driving. The average for the 5500km trip with the Kimberley was 14.0 L/100km (best 11.7 worst 15.4) - 2500km of this was on corrigated dirt roads + a bit off sand off-roading here and there.
We have a 50mm ARB/OME lift & 235/75 BF Goodrich AT's & a TJM nudge bar fitted.
Overall very impressed with the KJ - not so with the OME kit but I'll comment in the lift thread on that. Cheers. BC
