2019 Coachmen Leprechaun Winterizing?

319MB is the model, sorry i'm just now getting back. I will try and get some pictures of all the valves i've been able to find! I put in a call to dealer we bought from and also to coachmen but haven't heard anything back. I did remember I videoed when they walked us through. I looked at them and found more valves under the fridge and under the shower behind panels! Not real sure who was the brain behind that but seems they could of made it easier to get to! Old folks might have a hard time with these placements! Anyways i'm thinking that I may be on the right track. I'm sure I will still have some more questions before all said and done!
Thanks everyone for helping.
