Need?

Tough to say, but the airbags certainly do make the truck more pleasant for a variety of towing/hauling jobs. I have two Tacomas and put airbags on both. I installed a flip-up license plate bracket, relocated the 7 pin behind the license (so it wouldn't get broken off off-road) and installed the air bag fills on either side. I have hauled trailers up to 5000 pounds using the factory hitch with that set-up and the truck handles it well. The airbags also allow you to put some air in when you are hauling heavier loads in the bed so that it doesn't sag excessively. No load / trailer, drop 'em to 5 psi and the truck rides like stock.
