I just received new 36CKTS. Here's what I recommend:
DO get the dual pane windows. They are nice!
DO NOT get the cord reel! A) it is too flimsy to hold the anaconda cord, and B) they give it to you anyway (we didn't order it and we got it).
DO get the trail air hitch. It isn't enough for me, but every thing helps when towing
DO get the residential refrig, the 20 cu ft model. You will regret not doing this one.
Bathroom sliding door is just a 3 part sliding door. Works great. Not sure your question, it's a great shower and door. You do NOT want to lock a shower door!
