Yeah I feel like if it is crash compatible there's no problem. You could also let current truck owners be grandfathered in and have no new trucks sold to the general public.

There's really a ton of options other than just letting people get bigger and bigger trucks that really just kill more people.

Absolutely. Extremely few people need a truck that size full time. I was a cabinetmaker for years and I actually needed a truck so rarely that I saved a ton of money just renting one every few weeks and had the option to get a van (which is what most people really want anyway) if I needed one too. Most proper home renovations require a permit so you could tie that to it. I actually had a lot of options for free lumber and sheet stock delivery which is a huge time and money saver even it in the boonies where I lived and of course to my shop in the city. Most people really don't need a truck, they just don't take advantage of the services offered to them.

Any home owner should own a truck. I don't, but I'll say that my Subaru identifies as a truck (regularly haul trash in it, have used it to move bucked up logs about riding on the bump stops) but I have on a couple occasions had to borrow friends trucks. If I didn't have friends with trucks, id probably have to get rid of my jeep and replace it with a shitty lil ranger or s10 or something of the sort.
