True! I personally have My hitch adjusted properly. However My spring bars are for a much heavier trailer than I tow. I know from experience that My ride would be much better if I had the right rating for My bars.
Thinking about adding one to my Class C now that I am towing a trailer for the Jeep and solar panels and inverter generator......
You might wait till your pocket is a little lighter so you can judge what you need
if you'll look at the stamped hitch weight class on for example a 500lb max wt. hitch you'll find another wt. which is (~750 lbs. if used with a WDH). So it does take weight off the hitch, throwing (distributing) by means of rotational torque (momentary force) part of it forward to the front axle and part of it rearward to the trailer axle. if a WDH isn't raising the rear of the tow vehicle and lowering (applying downward pressure on the steer axle) then it's likely either too small for the job or not set up correctly. Your tow vehicles rear axle is the pivot point when you lift it with the spring bars, the levers (TV frame+Trlr frame) transfer that momentary force (weight) ~20-25% forward and ~20-25% rearward.
