Welcome from NY and congrats on retirement and the new 5er. You're in for a lot of enjoyment.
I've towed trailers of all lengths and types for many years but the fiver was my first 5th wheel. I was a bit surprised at first how much different it tracked than a bumper pull. You just need to turn as wide and possible and always watch your mirrors. Parking lot practice is good advice. I had a closed business with a vacant parking lot near me that helped as there was no traffic at all. Sometime a church near by will let you practice on a weekday when the lot is empty. Get a few traffic cones and set them up and learn about backing into a spot I have to admit I still struggle with that.
Read this forum regularly and you will learn much from the wisdom that is here.
Happy trails.
