Ours is an ACE, but most of the same issues. The throne is perched up on high because of the black water tank. Similar problem with the shower; it's an even higher jump. At 6' 1.5", even I find it a stretch. DW is shorter than you, and wasn't happy.
Walmart had an exercise step that works for her for both bed and throne. I could wish for it to be a touch shorter in length; I usually trip over it when rounding the corner of the bed, but then, I'm not really self correcting. For the shower access and other aids for tall stuff, we found
this. Sturdy, lite weight, and fits in the shower when not in use.
