2023 Keystone Alpine 3790FK. Basically brand new. Traveled twice. Has 3rd AC unit installed in living room. Upgraded the kitchen slide control with a newer Schwintech model. Shower door removed and added curtain. Upgraded kitchen and bathroom walls. Purchased the unit then wound up buying land and our focus shifted from wanting to travel and camp to needing to work on the land. Being stored under covered awning. Still under full warranty.
