Payload of 3,152.
Add two passengers (@ 150 pounds each) payload is down to 2,852
Add 200 lbs for hitch and 2,652 remain.
So far so good. Add more passengers, pets, fire wood, or say a tool box full of stuff in the box and you are getting into close to maxed out weight territory.
And to byronlj; it does make math a whole lot easier to just say 200 pounds instead of figuring 143 pounds or whatever. Besides, always better to over-estimate in this case, cause it gives a person more room to move with the other weight items to figure out.
