You are going to love the 270BH, we love ours so far. Great floor plan as it offered us a great middle road option between being too small and more than we were willing to pay for. Hope it's everything you expect it to be and then some. Our kids love it and can't wait for that next trip (and they always ask).
Health related issues always seem to give us different perspective than we held the prior day. Been through enough myself, with my wife too, that I understand where you are coming from and can be sympathetic to the decision you have made, a good one at that!
Happy camping, may all your trips be memories never to forget.
