I have a Tacoma. They are very soft sprung trucks. Mine would need alot heavier springs to haul a camper.
I'm not intending to haul a camper with my Tacoma, but heavier rear springs and full set of Bilstein shocks are in my near future plans, regardless, as are LT tires, to replace the P passenger tires it came with.
I like a truck to ride like a truck and not squat way down when I load it. I upgraded my Ranger in the same way and have been very happy with its' heavy duty rear springs, Bilsteins and LT tires. :)
