Mine has full unimpeded bathroom access during travel (it has its own door) - I've never used the bathroom during travel. I always use rest stops, gas stations, etc. One a list of the 100 most important things for me to consider in a RV, bathroom access during travel wouldn't even make the list.
So you're traveling down the freeway at 70 mph. What are you going to do, pull off on the shoulder to use the bathroom while traffic flys by at 70-80 mph - I don't think so (at least I would never do that). Rest areas or next exit always seems to have the accommodations needed.
