I noticed most here vote for the dry bath but not me. I like the extra floor space in the camper with the wet bath and it is NOT necessary to dry it after a shower. I simply take a small squeegee and dry the floor then throw a small carpet down. Open the vent and the door and it will be dry in no time. Takes all of 60 seconds or less to dry the floor. I've never dried the rest of the bath. For me, having more space in the camper is much more important than the 4 minutes I'm using the shower.
One question you did not ask is about the size of tanks. Unless you will always have hook-ups, don't overlook the size of the tanks. Many campers have puny tanks that only allow you to dry camp for a couple of days.
