Yeah, they are very different. the camry has a 3.5 and the 4Runner has a 4.0. But I love the 1gr-fe in the runner. I have an 09 SR5 and it is great. 167,000 and going strong. It tows nice and I constantly get 19-20 on the highway, even with a roof top tent. Towing, I get, depending on the trailer and what I'm hauling, 15 to 16.
