FYI, I just measured the ceiling height on my 2018 27-5L and at the outside edge of the bedroom door it is six feet four and one half inches. You can't walk that close to the outside, since the door frame is there, and these have an arched ceiling so it is taller towards the middle. These also have a flat floor from the bathroom to the bedroom so no steps to deal with in the middle of the night.
Oh yeah, this is one of the only companies to have the bathroom doors work the correct direction so you don't have to balance on the edge of the stairs to get into the bathroom, or darn near walk into the bedroom to get into the bathroom. I talked to a factory engineer at an rv show and told him they screwed that up, and he said they had the door open out so you could have privacy when you were leaving the shower to go to the bedroom. That made sense, but we have never taken a shower when we had company, and we can just use the door to the bedroom if that were an issue.
