We only have one bath (35’ coach, two people) and at times on longer trips I wish we had two, but really its probably only a couple times a month and has never been crucial. I’ve always though if we were going to full-time I’d want a second bath, but I’d also want a bigger coach anyway. But my bigger priorities are a long sofa and a big kitchen, both of which we currently have. Our longest trips are between one and two months and we get by just fine with one bath.
