I have the same unit. I have been full timing since md-July. I, like you, love the large living room. I am still trying to figure out the pantry and storage issues... guess it takes time to adjust from a house to an RV.
I am so amazed and delighted with your family. I cannot imagine moving this 43-footer. Good for you!
