I'm nearing the end of a 5 month addition.
We gutted the dining room and kitchen then knocked down a kitch wall to make room for an additional 72 square feet of kitchen space and added a 600 SQFT family room on the back that we are about half done putting the floor on. Once the family room is done we are putting hardwood in the living room, dining room, and hall way. I also gutted one of the bathrooms about a week ago and I'm going to be putting ceramice tile in there and the kitchen.
I have seen tons of people install hardwood and ceramic tile flooring and from what I seen it looked like fairly simple work just time consuming. Now that I am doing it myself I realize I wish we wou;d have hired someone to do it for us.
Be thankful you're only out in the RV for 3 weeks we havent had a kitchen since early January if food cant be bar b q'd, microwaved, or bought at a fast food chain I haven't been able to eat it since then. Not to mention washing dishes in the bathroom sink sucks ass.
Good luck!.
