I am sharing with you the business of my friend's parents. Her parents purchased 5 trucks and 2 bulldozers. My friend's parents are rich. What makes them rich? The city and local governments rent their bulldozers especially when there is a ferocious storm and the roads need repair, so the government may run out of bulldozers. The government includes renting trucks to discharge stones and rocks during landslides. They have a lot of equipment for rent and their hoe's gate is computerized. If you have money for capital at least 1 or 2 truck/s do invest in this.
