Jayco Hummingbird MBS??

I'll just say that he's not going to be very comfortable with the shower in a light unit. I'm not sure if there are any full profile trailers as short as 19' but you might want to look around. I'm 6'2" and I'm super crowded in my RV shower, 3" more height would make it ultra cramped. Make sure he steps into the shower and spend a few minutes in it simulating washing. I end up using the facilities at the campground most of the time because it's so uncomfortable. The only time I've really used ours a lot was when we spent a week in Yellowstone and the shower facilities were pay by the minute.
