Is this "chucking" effect at its worst when slowing down/braking?
I have zero experience towing a 5th wheel, but the only time I noticed anything similar with my E19 was when it was brand new, prior to having the trailer brake gain fully dialed in.
I had to set the gain very high immediately after delivery, when the trailer brakes were brand new. Braking action suddenly became very grabby as they started bed themselves in after a couple hundred kms of towing. They finally smoothed out a couple hundred kms after that. I found myself having to constantly adjust the gain during this transition phase. The trailer would noticeably buck on downhill grades if I had it set too high or low. However, the problem resolved itself once the brakes bedded in and I could finally set the perfect amount of gain.
Adjusting the tire pressures seems to have largely resolved the jerking issue. At pickup the trailer tires were over inflated at 56psi. I’ve dropped them down to 50psi as per spec. I’ve also raised the TV tire pressures to 40psi.
The jerking is pretty much eliminated. Think I will add some rubber shims between the hitch and the rails to eliminate any residual movement, and probably get the balance checked on all the trailer tires.
Thanks for all the suggestions folks!
