There is no reason you should be exposed to volatile compounds from a normal parked rental truck. I would have asked for another truck or avoided U-Haul altogether.
Agreed. It was actually another national moving truck rental brand (not U-haul, I was just using it as a generic descriptor). I don't know why I'm not mentioning it since it seems like there's only a few national brands, but it's not their fault they have to use DEF and the truck was really great otherwise.
