I don't know why wet baths get so much negativity. They spare precious floor space in a Class B. Wet baths are designed to get wet. They usually have, if properly designed, a pull current surround exposing just the toilet and the floor and protecting the vanity, mirror and walls. A good raised teak floor or similar so water goes through to the base floor can take care of that and the toilet can get a thorough cleaning that you can't do or desire to do by hand. Also you can use the toilet seat as a bench.
One of my passions is I seek out restaurants around the country and make it a point to have regional fare as I am a road foodee and a longtime member of Roadfood.com. That's a benefit of travel, IMO. You don't have to use their bathrooms. The smaller the town and the independent (not chains) the restaurant the better. I've met several owners and made friends that way, and even boondocked overnight in their parking lot at some restaurants you can actually park in.
You have a more intimate view of America that way other than scenery.
Of course we prepare and eat our own meals. That is what camping is also for. You have a galley and a refrigerator but you don't have to prepare and eat in the van. That is not desirable other than microwaving or cold sandwiches, percolated coffee and such. Bacon, though I love it--NO. Campgrounds generally have picnic tables and fire pits or you can carry your outdoor prep.
You have to look at the positives of Class B'ing. It is more difficult in a Class A, C, 5th wheeler or trailer, and tenting you do have to use bathrooms, and prepare and eat meals outdoors.
