Pick-ups didn't used to be huge though, see the S10/S15 for instance, a modern-day Colorado/Canyon dwarfs an S10/S15 from the final year they were sold in the US.

Adding a few extra hoops to jump through could be similar to abolishing pickups while still allowing reasonable exceptions, maybe requiring extra drivers training

• At the same time though, if someone needed to pull large trailers for whatever reason, but didn't need a full-on class-7 or class-8 rig and the CDL requirements that go with that, they could just use a class-5 or class-6 chassis-cab rig for that purpose and then use a van for various field work or picking up small amounts of cargo. That van for field work would even be preferable both because of having the ability to lock one's tools up and also having a sheltered workspace to do things in so they don't have to get rained on and the like, and can work under A/C or heat during a particularly hot or cold day.
