Well said, but the bath is not necessarily in the rear. I just traded in an Alpenlite, the bath with sep shower was pass side forward. Kitchen and dinette slide were at the rear.
For use, a dry bath is so much better, the wet bath is just that. We have had 4 TC's, 3 with wet baths, and we only used our inside shower facility a few times, relying on the CG's or the outside shower. The last TC had the dry bath and we used that every time.
It all depends on where you will go and for how long.
