I have the 30.4. Love it! With slide in, everything is accessible. The frig door and bathroom door (across from each other) open enough to use just fine while traveling but touch the opposite wall when opened fully. Also with slide in you cannot walk around the right corner of bed (as looking at it) to get to cabinet. Other than that nothing blocked. When traveling we put a door knob cover on bathroom door so it doesn't scratch or dent the frig door and vice versa.
