No idea @bigcol ... After towing with a V8 petrol 100 series and working out the consumption on that I haven't bothered working it out as the Prado "must" be better!!!whats the consumption comparison with your 120 V6 @dagree ????????????
Tell a lie. Did calculate one trip to Busselton and back with 50% towing and 50% not and worked out around an average of 16 - 16.5/100.
Not owing I average 14 so guessing it would be up around the 18 - 19/100 while towing?
