I think it might be right. My manual says 3415 as curb weight. So here's how I think it's pretty accurate

3415- stock weight
-50 - difference in rim/tire weight(convo pros)
-15 - No front sway bar and mounts
-8 - Mooseball removed
-35 -spare tire and jack removed
-7 -difference between alum driveshaft and stock one

3300lbs. I would imagine it's within atleast 30lbs or so. -Mark
