I've towed mini-ex's on equipment trailers, skid, steers, enclosed trailers, big heavy wakeboard boats, etc with my 07 Tundra TRD Limited. I hauled my 53 Farmall Super C tractor back from Georgia with a 3 row disc in the bed, 5' bushhog, 3' bucket, box blade, and a runner planter assembly. I think I tipped the scales just shy of 10k. The trailer didn't have any brakes and that was really the only bad part of the whole trip. Only bad thing is the gas mileage when towing that heavy. Truck squatted a good bit but it's to be expected, no airbags or anything.
