How much weight can you carry?
I know most trucks can carry a little more than they say, so I'm wondering how much weight have you been able to carry in your truck, and what config are you driving? I was driving a demo 2011 Lariat 150 5.0 ltr Screw with a 5.5' box. I put 1900lbs in the back today and was amazed at how little the truck really sagged. I know this is over the limit, and I only drove 6kms and carefully. My truck has the 6.5' box Screw and I think with airbags I should not have any problems carrying my camper.
