Trying to decide the right size MH for full timer

Some have done fine with 40 footers in some National Parks, however full timing you want room, I have a 33 foot with 2 slides its roomy and does get around easy BUT I would not like this size full time, 36 foot with 3 slides would be a nice size, not to big but big enough for 2 people full time.

I agree 40 foot is just to big in many areas.
