2020 4700 SW series Electrical Problems

Received this truck from the factory in January. 3100 miles on the odometer when I got it after it was driven to the Eastcoast from Oregon . Using the truck in a logging operation the truck has been a nightmare. First the wiring harness shorted out. Two weeks at the dealer (No logging).Then after a short period in service the MCM crapped out. Technician spent two days in the field diagnosing and fixing issue. Less than a week later ACM crapped out. Towed back to dealer second time. the truck now has 4400 miles on the odometer. Guess I should have gone with Mack, at least when I started my old Mack it kept running and getting the job done. Anyone else had similar issues???
