    Based on experience hauling heavy loads I believe that Toyota has built in a significant safety factor. Last Friday I had 31 sacks of corn (1550 lbs), tool box, chainsaw, ice chest, gun, and other misc stuff including myself and everyday gear including floor jack. Probably another 300+ lbs.. Truck was squatting but not significantly.

    I haul heavy loads all the time. The 1/2 ton Chevy Z71 I had was a sissy compaired to the last 2 Tundra's that I bought.
    I THINK THE SUSPENSION IS MORE LIKE A 3/4 TON.

    The amount your truck sags isn't an indication of payload capability. You can put some air bags or beefier springs on to prevent sag - but your payload is still whatever it is on your door sticker. The GAWR and GVWR are still the same.

    The Tundra rear axle is fairly beefy - but it isn't a 3/4 ton axle.

    But, carry on. Ignore safety warnings and ratings and continue overloading your vehicles. :facepalm::frusty:

    I'm not advocating for knowingly overloading one's vehicle, but the Tundra has a 10.5" ring gear (equivalent to Dana 70) in the rear. If that doesn't qualify as heavy duty, I'm not sure what does....just my .02.

    There is more to the rear end than the ring gear.

    Tundra 10.5" rear axle weight rating is 4,150 lbs.

    A Dana 70 weight rating is 7,500 lbs (or higher depending on config).

    As I said, the Tundra rear axle is pretty beefy ..... for a 1/2 ton.

    There is no reason why the Tundra can't handle those loads. I am actually surprised that the full size trucks are 1/2 tons and 3/4 tons.
    In other parts of the world Toyota Hilux and Ford Rangers are 1 ton trucks. Maybe the leaf springs are beefed up a little but the chassis, axles etc. are not near what any full size truck in the US is.

    This is 3 yards of mulch, so I'm thinking ~2000lbs? Pulls fine, just sags a bit. (a lot)

    I got this from this site: http://mulchstoremn.com/faq.html

    "Typically, mulch products weigh between 400-800 lbs. per cubic yard"

    Learn the diference between a “full floating” and “semi-floating” axle, and it will make sense. ;)

    BTW, one tons ARE light duty - heavy duty would be 46K lb drive axles. :D Or 69K tri-drive. :rofl:

    Steering was fine, not even noticeable. Seems air would help level my towing too... so probably next mod.

    Air bags are inexpensive and easy to install to help level the truck. As long as you don't go crazy with the load.
    I HAVE AN '08 that I load the bed full of camping gear and then hook up a 26 ft. RV AND drive 620 miles each way
    To Terlingua ranch in south Texas. Been doing it for 9 years with no problems at all. I kept the '08 and just bought
    A 2019. Heading out again in November with the new one. Only thing I'm not sure about is the integrated transmission
    coolers on the new Tundra vs. the cooler bolted to the front of the radiator on my '08.

    I'm curious after hauling all that mulch, have you noticed your bed drop slightly in height? I recently hauled about 1200lbs of flooring with my 2017 Tundra TRD and I noticed a slight drop in height in my bed. Especially towards the tailgate. No one else notices, but since I drive it everyday, I can tell. On a quarter of a tank, I've measured from the ground to the top of the wheel well of the bed. Driver's side is about 39 1/2". Passenger side is about 39". Two Toyota shops says that it's within standards, but I'm wondering if they don't want to do the work to fix it since it's still under warranty? These are the same guys that think that a slight leak (they called it seaping) in the rear differential is normal and just tightened the bolts. Thanks!

    I'm beginning to think Toyota is being a little overly conservative with the Tundra ratings. Down south of the border, they are not afraid to put such low ratings to a real, live test. :D

    Usually the “Toyota Lean” is on the drivers side ~1/2 inch.

    Things to look for:

    Flattened springs

    Damage to other suspension components

    Frame damage (highly doubt that)

    What landphil said! Half tons are all semi floating, thankfully we don't have c-clips holding the axle in. I see those around these parts fail when our local firewood guys overload their truck and the c-clip breaks and lets the axle and wheel out of the housing. Or the axle just shears at the wheel and the driver breaks out in a refrain of "You picked a fine time to leave me loose wheel". If I need to haul in excess of payload capacity for the truck I will hook up to a trailer. If I ever need to haul large loads again it will say Kenworth on the hood. Or maybe Pete.

    Amount of sag does indicate how well the vehicle will handle. Start taking too much weight off the front tires and handling degrades I'm a hurry. I don't care what the door sticker says as long as my truck still handles well

    How well your truck handles is very subjective. You might think it handles well - others may not.

    I love how so many think that they know better than the people that designed the damn truck when it comes to weight ratings. As I said before - carry on and ignore the ratings. Effing frustrating.

    Best of luck.

    Either airbags, Timbrens or SumoSprings will help with the sag and improve rear handling while under heavy loads or towing but you should never overload your truck.

    That’s pretty much what I’ve always wanted Tundra-wise. Did you special order from the local dealer?

    I believe that the ratings are there to cover the worst case scenarios. If you exceed the load or towing capacity and never experience an emergency stop, an unexpected large pothole, or one of many other driving hazards, you are likely fine, but those unexpected things do happen sometimes.

    Keep in mind what those regulations say. Its no different than expiration dates on food. That was literally just in the news about the required dates have little to do with how long the food will last. Regulations numbers are regulations numbers, not based on some logical real world testing.

    I still completely agree I would never go past what the number says mostly so I wont be liable and I can always blame someone else if something goes wrong. But to think those numbers are a reflection of actual truck capabilities is laughable.

    Personally, I installed the Sumo Springs (far less hassle than airbags, etc), which really smoothed out my trailer towing (bounce, etc). However, I still stay within the vehicle's load specifications.
