All passengers sans a few experienced pilots with quite a bit of time in RVs get the standard "wait until I come around and help you in/out before moving" instructions. No issues so far, knock on wood, but only a time or two when I've had to forcefully tell someone to STOP MOVING AND WAIT FOR ME to come and help you.
There are a lot of things that can get bent/broken/dented on any airplane, and most people are thankful that I'm there helping them find their footing, what to grab, what not to grab, etc., as I think they'd feel even worse than I would if they damaged something.
