Fugitive- In the event you end up not finding the sticker, there is a nice specs chart that may include your model here:
Even better may be to go to a CAT scale and weigh it loaded as you might expect to depart on a trip; e.g., full fuel, 1/2 water, empty black and gray tanks, 2 adults, etc.; then compare that to the GVWR. That way you will get both axle weights too so you can see how you are doing on front and rear GAWRs as well. "Real life" weights will include any after-mkt items a PO may have installed; e.g., hydraulic leveling jacks, Helwigs, Saft T Steer...... things the chart doesn't know about. Real hard data beats "estimates" every time.
