would it really need to be hauled off ? if its going to be yard a skid steer mulcher would make short work of it then you only need to haul the big stuff even one of those rental chippers with a 20 horse is soo much better than trying to pack a load of brush and then get it out. Oh I hope you have a hoe with a thumb to load the truck a skid steer simply is not going to work efficiently a few big logs on top can give a little weight to make the load slide but cant be over the tailgate hinge or even close everything will be hung up
Hiring a rolloff would be far better than a tandem
