Rear end bouncing/Equal-i-zer 4-point 10K hitch

Ok, I must have misread the ride heights originally. I could swear they both said 36.25"...

Sooooo, ignore my advice from earlier. It's not too much bar tension. Most likely it is not enough.

One universal truth of RVing is, the dealer never sets the WD bars correctly. The reality is, they can't. They don't know what you're going to be putting in the trailer. You need to go through the adjustment process yourself to get it fine tuned to your needs.
