I've seen conversion kits for old trucks under $10k. So there's your answer.

Unfortunately said kits are often lacking in range unless you're willing to fill your truck box with batteries, because you can't really retrofit a "skateboard" style battery.

I literally want that skateboard with seats and a steering wheel. Hell, give me a diesel burning heater and a washer fluid bulb I have to stomp on like I have in my old truck, I'm not picky
