Congratulations! Coincidentally I just got back from the dealership where I paid for my new blue P520. I won't pick it up until next week after the accessories come in and they install them. I got a roof, windshield, rear (fabric) panel, winch, 66" plow, mounts and front arm guards. Went with KFI plow, winch and mounts.
I was able to test drive it in the parking lot and it shifted abruptly just like you said yours does. I'm glad I read about that here first or I might have thought there was something wrong with my unit. Overall I'm pretty excited about it and can't wait to get it home.
I'm getting ready to place an order for 1.5 inch spacers. I'm swapping the relatively new ITP wheels and tires from my rancher with the wheels and tires from the P520. I will probably end up selling the 05 Rancher to make room in the garage. It's been a good machine and only has 575 miles.
By the way....I see you are also from WV.
