Pros
Decent pay if you are good at installs and have a good understanding of how houses are built. Depending on location, other installers that may assist you are pretty good people. A lot has changed with the company since I was there, so it sounds like the majority of the issues I had are now resolved. Minus most of your schedule, you get to be autonomous, and do some stuff how you want and somewhat when you want. New management is willing to pay a little more for quality workers.
Cons
If you are in a low presence state or region, there could be TONS of driving time. I spent many days and nights driving several hours to do one job. The old schedulers were not efficient, but that may be different now. The old salespeople would do whatever to sell a job, and not gather enough, or any correct information. That often led to longer, more difficult installs, and sometimes, more expensive installs and an upset customer. But it sounds like the old selling system may be gone, so hopefully that's true and all is well and more professional. You are responsible for cycle counts of parts inventory, and you don't get paid for the time that you spend pulling out and properly storing deliveries left by the carrier or Lowes. I once had to completely disassemble a bundle of 4" PVC sticks that a delivery driver put in my unit sideways so you couldn't access the unit at all. You never get your schedule until the evening before, so you can't plan anything in your life, because you never know where you will be, on what day. Lots of crawling in crawl spaces and attics.
