You guys are beyond helpful. We were just discussing it and I think we may steer away from the 1/2bath. The majority of what we do is long weekend camping. This summer, I have us taking 4 day weekends every other weekend or every 3 weeks at the most. All of the campgrounds have bathhouses if needed.
I actually just made the point to my wife- we are camping in it for a few days, not living in it. Our parents had 1 bath in their homes for the whole family to use when they were growing up. I think we can make it work for a few days at a time!
