I never operated a larger 'C' do I do not know how they handle. The HD sway bars that I installed helped with that side to side rocking motion.
As for getting up 3x. I know that trip. My corner bed floorplan has the bathroom sink outside of the shower and toilet area. Therefore the shower wall is shorter than a corner bath model that has the sink inside as well. I sleep on the left side of the bed so its easy for me to get in/out of bed having a short wall next to me.
Being that our foxhound changes her sleeping position a few times each night, stepping on a 75# dog in the dark is the problem. You know she's not quiet about it either. Foxhounds have that loud bugle-howl that they do that lets all the other campers know what I'm doing. :S
