I can easily believe the empty weight is 6020 lbs, and depending on the options it's probably more than that. I heard that Jayco went with a plywood floor instead of the lighter underlayment that we had on our 2014.
Our yellow sticker showed 5937 lbs empty. We found that loaded (ready for camping) the weight was give or take 6680 lbs.
Just to give you an example, here are the weights when we took it to a CAT Scale with the tow vehicle at that time. I have since moved to an Eagle 284BHBE and a F-350.
2012 F150 Stats:
3.5 Ecoboost, Max Tow, 3.73 with 6.5 ft bed
GVWR 7700 lbs
Max payload: 1685 lbs
2014 28DSBH Stats:
Summit Edition, 15K A/C, Insulation Package
Empty 5937 lbs (yellow sticker)
1) First Scale: F150 only with family and full gas tank
Steer Axle: 3700 lbs
Drive Axle: 2960 lbs
Trailer Axle: Nil
Total: 6660 lbs
2) F150 with family, full gas tank and Weight distribution engaged
Steer Axle: 3520 lbs
Drive Axle: 3740 lbs
Trailer Axle: 6080 lbs
Gross Weight: 13340 lbs.
Hope this gives some real world data.
