I'm a newbie and was introduced to chucking yesterday bringing home our (new to us) '11 Cyclone 3850.
I'm pulling with a '12 Dodge 3500 DRW with heavy tow package and a B&W Companion hitch.
I learned from B&W that the tightening sequence when installing the companion can make a big difference. I used a grease plate after reinstalling the Companion and between the 2 I found a noticable improvement.
After reading the experiences here I'm coming to the conclusion that there really is no definite answer since there are so many variables involved...ie tow vehicle, trailer, hitch, suspension on vehicle and trailer, etc.
I'm finding out very quickly that I have a lot to learn as an RV owner!
