Brochure dry weight = 3040. Fine print says that does not include options such as air/con, awning, and also empty propane tanks.
Actual as I brought it home empty, 3500.
Actual, ready to camp ( empty fresh, grey and black tanks, full propane ), 4000. I travel solo, and I don't need a lot. Also, I don't boondock, I buy food and necessities along the way, so I never carry much of that kind of stuff.
There is likely about another 200 pounds of things in the truck though, counting tools, camera gear, bicycle and misc.
