Actually, the PHEV should give a relatively better economy when carrying a load than a fully ICE-driven vehicle.
The main increase in consumption when increasing the load is by the extra effort required to overcome inertia when accelerating - and on an ICE-driven car that energy will be wasted as heat when braking (ignoring things like wind resistance when slowing down and increased rolling resistance here for the sake of the argument).
On the PHEV at least part of that energy used accelerating is recovered through regeneration - making it more efficient.
