Running into a few defective components can be frustrating. I had a bad dash switch on the last 8kwh install we did. Fortunately I had a spare around. Enginer quickly sent a replacement.

For the modular cord, you could simply have Enginer send you a new one.

It's up to you about the toolbox tray. Some people leave it in, some people modify it, some people leave it out. As you noted there are pros and cons of each of these options.

The best option is what works for you and still keeps the system with adequate airflow. Basically if the system is often shutting down because of overheating, then you'll want to increase the airflow.
