Location of components on a 2020 Keystone Montana 3121rl

[daveclif]

Hi, bought a 2020 Keystone Montana 3121rl. I have a location identifying issue. Know where the controller is and wiring bundle. However inside my electrical panel box is located above coffee bar(walking in). On Utube video's show on wall eye level by Bathroom door. However No sticker to befound there nor is there a sticker for display wiring location above behind or on top for sticker. Has anyone with this setup location with panel switches know possible where display locations might be ? The heater control and fan control is located on coffee bar table. Live 55 miles from dealer and guessing maybe they will tell me. Most appreciated advice if any. Possible pulling back electric panel in trailer where a lot of wiring is going to switches, will have someone else do the roof panels because of mounting location.
