try too wait for the new d max ... since heavy duty hauling need mo which torque is needed .... di mo kailangan ng comfortable ride na offer ng navara better off go with the d max because pang heavy duty siya but if you can wait for the all new d max much better it will offer more... bigger and more power full..
