I have a 2003 Tundra and I don't have a owners manual. I looked online and found a site that says the towing capacity is 7100 lbs with the towing package. I'm thinking about buying an RV and I was wondering if anyone uses there tundra to pull one. I'm thinking I would like to get about a 23 footer. Also does anyone pull anything bigger. I don't want a 5th wheel. Any input would be helpful.
