Hi just to add to my earler post. My toco is a 2004 v6 3.4 4door with the short bed. I drive with the od off and try not to drive faster than 60. My rpms run around 2800. mpg around 12.5. The manual for my truck and sales book have my payload at 1650lbs. My friend has the 4cyl man reg cab. He runs in 4th gear and is getting better than 17mpg. My camplite 5.7 wt sticker reads 900lbs I know its over 1000. My guess most stickers are wrong. I was very pleased how well my toco handled the mts of NC, W VA, Va, and Tenn. I have been all over from NJ to FLA and NC coast to AL. I have driven well over 4000 miles since sept 2012. My toco steped up. Bill
