I have a 2016 3/4 ton GMC gasser with Anderson hitch connected to a 32' trailer that weighs 12.5k with about 2100lbs pin weight. When traveling I get a jerking in TV when there is a load. Happens going up a hill or slight elevation in road. Usually felt more above 30mph. I have a cushioned pin box and Morryde Cre3000 added to suspension. Is this "chunking" or do I have an issue with slipping tranny or chugging motor. Can't see tach moving. Never happens on down hills or full throttle pulls up hills. No issues noted when not towing. It can even happen on smooth roads. Its not constant but happens enough to be annoying.
I have a similar truck and trailer setup - 2015 Chev with Duramax. I assume you have a standard (short) not regular (long) bed. I have the short bed. I also have the B&W Companion and have looked at the Anderson. The reason I haven't switched is because when I first got the 5th wheel the chucking was awful. The B&W has a lot of adjustments and I experienced with a lot of them until I found a comfortable position for the hitch. I believe this was the majority of my problem. I still get some chucking but having a full tank of fresh water helps it to pull smoother. It seems that my rig might be nose heavy as the fresh water is in the back so it would lighten up the hitch. I think the chucking comes from the short wheelbase.
