On the unibody thing: Out of curosity I posted an inquiry over at RV.net several months back asking if anyone there had personal knowledge of a "modern" unibody vehicle being damaged by a WDH. Thousands of RV types visit that site and I was surprised that the one response was of a framed (not a unibody) vehicle that was likely far overloaded. There were lots of opinions of course but no examples. There may have been incidents since then but I haven't heard of them. Maybe someone here knows of one.

IMO the problem is that minivans are car-based and have grown so large that they do well to handle their own weight. They are likely not designed as beasts-of-burden. Just my $0.02.
