I keep pointing people to rvusa to look at floor plans. That way you aren't wasting time & going nuts walking thru dozens of rv's. Some of our must haves were front facing kitchen sink,bathroom door that did not open right into the refrigerator, cab over entertainment center (C Class), dinette across from couch to name a few.
Good luck making a decision!
