I bought the all weather mat for the rear cargo hatch, behind the third row. It's very nice, fits the area perfectly and has the Chrysler logo. I also bought the storage bin for the rear cargo area. I use paper bags from the grocery store, and it has 4 sections to hold the bags, so they don't fall over. It works well and I'm pleased with it. I also installed stainless steel door sill guards on the front door sills. They are quality made and have the Pacifica logo.
I haven't seen the protection package you're referring to, but saw the all weather mats Chrysler makes for the second and third row, along with a runner for between the second row seats. I was impressed by the quality and the lips to catch excess water. I want to see what the WeatherTech's look like before making the purchase.
