You would be well served by any of a number of small diesel trucks commonly available in The Rest of the World. Unfortunately, such vehicles are not sold in America.

You are left with the issue of having truck things to do, and also happen to own two trucks. I'm thinking using trucks to do truck things is the obvious solution. How far do you have to haul this stuff?
