Since you already have the system, go ahead and use it. At least try it first, you've got nothing to loose.
Your objective is to distribute the weight to the front wheels of the tow vehicle. Although the bars are for 10,000 pounds, if you don't apply so much tension on them, those bars should make for a little softer ride and still throw the weight to the front. At a certain point if tension is loosened too much, they serve no purpose. So you need to find that sweet spot. That will come by trial and error. If your bars have chains on the end, try adjusting by raising or lowering one link of chain every time you take the camper on the road. If yours has a fixed bracket the bars rest on (like an Equal-i-zer system), then you need to tilt the head of the hitch so the bars are angled down or upward slightly, adjusting the tension.
Either way, I suggest to give it a try first. Also, by the time you load up the camper with everything, you'll find the camper ends up being much heavier than you may think. A slight over-kill? I REALLY do not think so.
