Our Wolf Pack weighs about 5k, tw dry is about 500. But after we load two 600# ATVs up there I anticipate at least 1500 tw. Hope more is on tt axels, but my dually with a Reese Titan class V should handle it. My question is, it looks like a 20% or maybe more tw. Has anyone any experience with a number like this? I'll get the proper wd setup, and another question is, with that tw and a dually, any need to pay for sway protection?
