In my opinion, to give you a better answer specifics of your set up like what the tow vehicle is and what the trailer is would be helpful. Also, what type of WDH are you using?
I towed the trailer in my signature with a 1/2 ton Suburban. Everytime I hooked up I had to adjust my Dual Cam WDH because I was pushing the limits of the trucks suspension it seemed like the change of 50# in the trailer changed the set up.
I can tell you that with my 1 ton van I did the initial set up and I haven't had to touch it since. Two weeks ago was the first time the trailer really was packed much different than any other trip. We had 5 full size mountain bikes (4 inside, 1 on the back) and all of the additional stuff we packed for a 6 month old. After hooking up and checking my WDH, there was no adjustment needed.
