Towing 6-7000# Trailer with Toyota Tundra

I had an 08 Tundra sr5 crew cab with the 5.7 and towed a 7500lb trailer. It did great with the weight and pulled fine, like everyone has said the payload was the Tundra's achilies heel, with the family and all the normal camping stuff we were over payload otherwise it was a great truck and I enjoyed it, wish they would make a heavy duty payload pkg for it. My Ram 2500 has twice the payload and it is nice not to have to worry about it anymore but I do miss the Tundra.
