Anyone have a wife who overpacks motorhome?

I had that problem with relatives traveling on trips.

When the relatives started bringing piles and piles of stuff I would make them weigh it. Whatever their stuff weighed meant that amount of weight had to come 'out' of the MH 'before' any more of their stuff came in.
Caused a few arguments between them over who's stuff was more important. But I was not part of the equation they had to figure it out themselves and I had a clutter free MH. And my coach was not overweight with a bunch of unnecessary stuff.
