"Truck" tires are NOT worth looking into if you consider rolling resistance important.
Not only are they designed with "truckiness" in mind - that is, heavier duty load carrying capacities, more tread rubber, and therefore more mass (and more rolling resistance), they also have tread compounds that are more oriented towards more rock cut resistance, more unit loading, etc - all of which hurt RR. In other words, it's all about treadwear and traction and RR really hasn't becomes a design factor in truck tires yet.
