“Fleet maintained” = got greased once a year whether it needed it or not and has had an oil change or two in it’s life time, not to mention 1000 different monkeys beating the ever living #### out of it
It's in house. All the trucks I saw when I have run seasonal with them have APUs. They are very driven by fuel mileage. A lot of drivers have been on for 10 or 15 years. They are issued thier truck and they keep thier truck for a couple of years or 5 or 6. The most senior get new ones over any one else, they can dump one after 2 or 3 years.
