Unless you have bought the truck already I wouldn't buy it. I'm a FORD guy but if your going to pull a RV you got to get a diesel. You will get 5MPG with a gasoline V8(pending size of RV) Thats one reason the price is so low. I have lots of experience with large towing and years with diesel and gasoline engines. I would be a great truck for other things like offroading but large towing jobs you will fill it in pocket book.
