If you're a Facebook user, there is a huge group called "Fulltime Families". Lots of folks are stationary fulltime.
There's not a whole lot to say- trailers aren't well suited for living in, so expect little quirks to pop-up. Don't expect fulltiming to feel like camping- it's now your home, think of how you live (are you outdoorsy people? do you mostly stay inside?).
Who knows- maybe you'll like the simplicity of the life and will want to do this long term.
