Full Timing Married Couple in the Back Yard

We are new to this - RV's. About a month ago purchased an '04 R Vision Travel Lite, 27 foot. My daughter and her fiance' will be married in May and will live full time in our back yard for about 3 years. They plan to work as RN's, save money and then put down on a home. We like the idea, and we certainly don't mind helping them out their first few years.

Just wanted to introduce myself. I'm glad I found this forum - tons of info here!
