I tested my 04 Tundra's payload last weekend without thinking about how much weight I was putting in the truck. I didn't remember what the specs said payload capacity was and I probably wouldn't have done this if I would've known what I do now....BUT my baby hauled what I estimate to be about 2350 lbs!!!! That weight consisting of 30 4x4 treated posts (est 25 lbs each--very heavy when soaked with the pressure treatment) and 20 bags of 80lb Quickrete. I was just a little concerned at how low the bed was riding, but I did have all the quickcrete sitting over the axle. When I got home, I thought to myself I just hauled a serious load here and I should look up the payload capacity. Well, now you know--1 ton, 350 lbs for 20 miles--no problem!
