I don’t know about your state, but here in WA you can rent a “commercial” big box truck from UHaul, Penske and others with no CDL. I rented a 26 feet box truck for my move and drove it around town just fine. They do care about damage, but they don’t consider scratches to be damage.

This is just wrong. Besides Home Depot, who aren't going to literally sic the gestapo on you if you use it to run a 2nd errand, there are plenty of companies that rent beater trucks for hauling anything you like.

You can rent from U-haul and use it as an actual work truck no problem.

I damaged a U-haul once and it was fine, it was all covered.

We rented a U-haul this year and hauled about 2000lbs of stuff to the dump with it in one trip.

Home Depot et al also rent pickup trucks by the hour (something like $20) and they're quite capable and nobody checks the paint.

As long as you bring it back and it's not on fire they're unlikely to care.

You can even optimize by buying your own trailer so you can load and unload at your convenience, and only rent the truck to move the trailer - and trailers (even enclosed ones or dump ones) are significantly cheaper than trucks, and really only need tires as maintenance.

your comment is flat out wrong. Lots of places will let you rent a pickup truck and use it for work - that is literally the point of a pick up truck.
