Good advice there from Old-Biscuit!
Yes, load your truck ready to camp and weigh it. Sounds like you have the FW hitch installed. Be sure to weigh just the rear axle as well, to see what you have left, before going over RAWR, and max tire rating.
The dry pin wt seems wrong for the unloaded FW wt of near 12,000. OBs example of 2,800 loaded pin would be close. You are likely to be over GVWR of your truck. You decide comfort level there. You need to stay under RAWR/tire rating.
IMO this FW will be a tight fit for that truck, but the scales will tell the story.
