I bought this truck new in 2007 after driving a few of the competitors and decided to go with Toyota because of its known reliability and large towing capacity. I had an accident a month after owning the truck and it still drive the same after repair.
I bought a 10,000 pound 5th wheel and have hauled it to Yellowstone and the Appalachian Mountains with no problems.
Sure gas mileage stinks while hauling (8-10mpg) but its a truck.
While my comrades pull their trailers and start complaining their transmissions are getting hot mine doesn't even flinch. I hope this review helps eliminates any doubts about buying this truck. I also don't notice a jitter but I'm not a professional reviewer.
