12.5K 98412 is 51 lbs. http://www.quadratec...122_1211_07.htm
10K 98510 at 67 lbs. http://www.quadratec...122_1310_07.htm
I bet the weight difference is in the X2O additions Smitty brags about on their website...
The X20 Series features an all new integrated wireless remote control for ease of use and maximum versatility. The top-of-the-line X20 COMP also features Smittybilt's exclusive Dynamic Braking System which reduces drum temperatures by 66% and makes it perfectly suited to operate all types of synthetic ropes.
just got off the phone with their tech
the X2O has an additional cover over the casing that gives it the look & that adds the extra weight (& can be removed if desired)
the XRC is 20.8" long & the X2O is 22.3" long
