I guess if you're not in favor of using a large truck for these runs, you might want to consider a smaller Japanese kei car or kei truck. If you want electric you might look into something like the BYD racco or the Honda N-one.

Just to throw a different perspective. These are small, can be used to move a lot of cargo through rear seats reconfiguration, and can be an interesting choice. Not sure about electric kei trucks though.
