you sure? there was a thread with guys on here praising tacomas wood hauling capabilities!
one even said the 4 cylinders, as long as a manual gearbox, will pull
anything!
really the best thing you could do for it, is get a trailer to pull behind it for wood. its not going to take much to put the bed of a taco down on the bump stops, and its better to abuse a cheap trailer, than your truck.
1/2cord will bottom out a full size 1/2 ton trucks suspension, couldnt imagine what itd do to a tacoma! i guess you could get some helper springs for the rear, or even some air bags.. but then you still have an extremely overloaded truck, only without a bottomed rear suspension, and then comes the question of power/tranny being able to handle the load
