Fairly newbie here, having had our since September. Made many weekend trips. I have found the passageway akin to being on a sailboat passageway when heading to the aft king bedroom on our 37FS. Bathroom door will not open all the way, but easy enough to make use of at rest stops, etc. Passage to kitchen much the same, ample but not near as nice as when slides are deployed. I made a step cover out of wood of our dog kennel rides on that spot when we are underway, plus makes it safer for them as well. Many plans on the internet, I just used 3/4" plywood with polyurethane finish.
