Here's some more: we have 5 sets of Umbra-style hooks & cubbies in our 19. I say
style because not all are made by Umbra; they're look-alikes but had the right number of hooks.
All our mounted primarily with VHB tape. The longer ones are "reinforced" with a short wood screws barely entering the plywood facing where mounted. It's not because the VHB tape doesn't hold. Instead, it's because the Escape walls aren't dead-on flat; you need as much surface area as possible for the VHB tape to be effective
Do they stay put? Here's a link to my home made test of the VHB tape.

Having the hooks keeps everything looking less cluttered, at least in our Escape. Just made a trip out out to our storage facility, to get the snow off. Here's some pictures of the Umbra hooks:
