Here is my class A quad bunk motorhome. I have put much effort into it to make it comfortable for my family. We have 4 kids of our own and are getting ready to go out for a one year Odyssey. This motorhome answered our question that you pose. How can we have quad bunks with a separate bedroom and have privacy and be comfortable for a family. I used my knowledge of RV's to find what I think it an acceptable answer. Feel free to give me feedback. We have been RV'ing since 2007 and own two motorhomes.
