Learning curve going from 5th wheel to TT

I have logged thousands of fifth wheel miles, my wife and I decided to switch to a TT to allow us to carry our kayaks on the truck (easy to load). My truck is an F350srw 4X4 short bed, the trailer we bought is an 2021 Outback 340BH, 39 ft long empty weight 8787, tongue wt 1040. When we bought the trailer I hooked up with my regular hitch that after hitching up the top of the ball was about 2 1/2" below what was level on the trailer (the weight dropped the truck about 3") the springs were just touching the helper springs). I drove home and found the trailer was a real handful over 60mph, with sway issues starting (also 30mph side winds). Once we got home I ordered an Anderson hitch for sway control. I have a set of air bags that I am going to install.
I am wondering if I should set up my new hitch with the truck kept level, or slightly nose down when adjusting my ball height to keep the trailer level, or slightly nose down; or should I set the ball height with air bags at 5psi and adjust the trailer after loading with the airbags to level or slightly nose down. I am not terribly worried about my steering axle weight, so the hitch is primarily to help control sway and bouncing.
I am totally new to TT towing and it is an entirely different towing experience. Am I headed in the right direction, or is my thinking flawed?
  • The experience of many members has been that the Andersen hitch is better for lower weight trailers as it seems to have a problem transferring the weight with heavier tongue weights. If you want to duplicate the great towing you are used to with the 5th wheel then you need to bite the bullet and get a Hensley "Arrow" hitch.

    I towed with the Hensley for many years and never once had a sway event or even close to one. They are, hands down, the best towing hitch money can buy. Although they are about three times the cost of a "normal" hitch they are worth every penny spent in towing comfort, piece of mind, and safety.

    Sorry to say but you are towing a long, heavy trailer and the Andersen is not going to cut the mustard. You need a better hitch for that combination. Yes, your thinking is flawed in that the weight lost off the front axle of the tow vehicle is the major reason for steering issues and sway control. The WD hitch restores that weight and, along with several other issues, the control of the trailer is restored.

  • Park with ball under coupler, measure front bumper to ground. Hook back up, and check again. A large transfer of weight off front will change handling more than adding weight to rear. Might want to check all steering and suspension components for wear. A change in load can magnify any alignment issues you might have.
    Many RVers talk about the percentage of weight you need on tongue. Most will not mention that when you check it the tongue needs to be at the same height as when towing. As you lift it, the weight goes down.
    Is most of your storage in front of the axles? Maybe just loading your stuff while thinking about where the weight will be might solve the issue
  • You will need your TV's manual to find what they say your front axle/fender should be brought back to after setting up the WD Hitch

    Am not a fan of the Andersen WD and reports that they do better with lower tongue weights

    Won't ho into weight ratings, but say to stay withing your ratings and need to weight the whole setup axle by axle, loaded ready to go

    Main weight to watch is the TV's rear axle's actual vs RGAWRA...and actual tongue weight around 12%-15%

    The trailer should be level at its highest pointing and recommend pointed slightly down

    Ball height really doesn't matter...thecabove trailer pointing is

    Good luck !
