Steve, it sounds like you need a Winnebago to me...
Can you imagine the abuse that would generate

, mind you we have two more grandkids on the way so maybe....

15 grandkids sounds crazy but SWMBO has four sons from her previous marriage and I have two, so six sons producing 15 kids is only (!) 2 1/2 each.
p.s. I’m trying to get Christmas abolished

What a fantastic family you have around you, very rare to hear of a "proper" family these days, I sympathize with you over Christmas though a nightmare.
We have three grandchildren sprinkled around our three youngsters and we have a complete family day once in a while at an event such as Red Bull Air Race or a Duxford open day and it's good and pretty full on, this would take on a whole new meaning if you all had a get together.
We have a few Winnebago's parked up down here as temporary accommodation on farms prior to planning permission being granted, it's a well known loop hole down here justifying the need to be on site 24hrs tending livestock. They don't move so for that we are thankful as you say they are go large big time.
On the odd occasion there is one on the move it is a bit of a nightmare on our narrow roads I have to say, no different from the artics delivering our food though, we're big on patience in Devon

The SUV attitude I think comes about when we see Yummy +1 brat being transported around, whenever you see one packed to the gunwhales with kit or people it all makes sense unlike us owning three cars for the two of us
