I've never had an issue with our dual cam off road on forest service roads or going to dispersed campsites. Now one issue with a WD hitch is that spring bar pressure is dependent on the bar angle. so if you end up with the combo with a "V" at the hitch point (TV and TT above the ball) rather than on a horizontal surface, there is more pressure on the spring bars and it can get wicked unhooking if your not careful. (Or hooking up for that matter).
I have had NO problems with the combo not being straight when hooking or unhooking. the bars will drop into the cam's properly once you straighten out.
My take, if your existing WD system hooks and unhooks ok when you are offroad and rides ok, then the DC will be fine and really no different hooking and unhooking or traveling offroad.
