Although I won't disagree with your EV truck reliability statement I really love
Kei trucks, of which there are a few legal examples, one guy in California has a street legal 6 speed dual range manual diahatsu hijet in Cali that came from the parks department.
The Miles zx40st truck although unreliable is very cheap and very simple, it can easily be converted to a diesel by the right person or reprogrammed for speed if you keep it electric. The st is not a kei truck, 5ft wide but with a 9ft bed!
Some examples have sold for $500.

The miles zx40 cargo van may be big enough for your stuff and again is very cheap and 100% interchangeable with the stateside daihatsu charade 1liter car.
Again easy drivetrain swap to a daihatsu charade 5speed 1 liter gasser, 40mph cargo van.

If you are looking more conventional a Prius V might be big enough inside to go trailerless.

If you plan on having a trailer no matter what
1. Gen1 insight
2. Volt (used they are just as cheap as a Prius)
3. Prius lift back.

Also domestic there are class vw rabibit diesel pickups 50mpg all day
Ditto Subaru 360 sambar pickups, 50mpg all day and street legal and just cool.

Yeah I know my choices / suggestions are odd but if you have mechanical skills you could have a much more memorable ride that grabs attention in of itself making folks notice your advertising.

Also if towing with something that does not normally tow, pay a few bucks for a weight distribution hitch and trailer brakes.
From personal experience if you have those two things you can give the middle finger to the safety idiots since it will then always pull straight, never fishtail and always stop.
Best upgrades I've made and in my mind should be standard equipment.
