Well I have just done the left hand side of Australia in the Commer 11000 miles about 4000$ in petrol and 12 weeks on the road ,great trip .The Commer did do a head gasket about 1000 miles from home in the middle of no where ,so I remove the push rods and spark plug from that cylinder,drove another 100 miles on 3 ,to a town then replaced the headgasket .After that it went like a top ,2 oil changes 1 grease and 1 polish. As you can guess the old girl got plenty of attention were ever we went . So now I have done my bucket list thing of driveing around Australia in a Commer and what a trip it has been.
