I was raised in the mining business in New Zealand and Australia and have been around heavy equipment and mine and quarry operations all of my life. When I came to the US 40 years ago, I worked for Mack Trucks in the oilfields of Texas, Oklahoma, Wyoming & North Dakota. I've driven tanker rigs on long road trips all over the US and western Canada. I stick to what I know well - oilfield trucks and equipment and aggregates equipment such as ready mix concrete, dump trucks, etc. My customers like that I can talk in detail about the specifications of the equipment they are getting.
