but my in-laws keep saying things like it is very expensive, a hassle and other things to discourage this thinking.
Could it be they fear they will never see their grandchildren again? Their arguments seem flimsy, but maybe their true concern is unrelated to how much money you may spend. Would they complain if you bought a bigger (and more expensive) home near your current home? I would dig into this situation a little more with them and see if you can't uncover their true concerns.
I have a dear friend who full-timed with three kids two dogs and three cats along with her DH in a 30' class C. They home-schooled and the kids loved the whole adventure. Kids don't need stuff, or even a stationary home. They need their parents' time and attention. JMHO.
