Trying to decide the right size MH for full timer

Have you spent a week in a motorhome? From your post I concluded it is new to you. You will not know until you experience it. We spend 4-5 months in ours in winter. I have a 38 ft gas with three slides and washer/dryer. The opposing slides in living area are great. We do like being able to wash clothes in the coach. We think our Winnebago 28Q is perfect as do our friends with 45 ft Monaco os to each his own.
