Anti-sway bar

Love our WDH.

MeandAd, seeing you have the same pod we do it would be helpful to know what you are towing with.  We have towed ours with a '94 F-150, '11 F-150 and an '08 Explorer and a '13 Explorer.  The only vehicle that gave us fits was the '08 Explorer as we couldn't go above 35 mph without major sway.  So vehicle does play a part.  More importantly however and offgrid addresses this quite well is your tongue weight, get that checked out for safety's sake.  No fun having a pod swerving back and forth behind trying to pass you up.

In the past, I have found that most people, the first time they install a WDH, they end up taking too much weight off of the tongue.  I would suggest that you lower your L bracket one hole and see how that works.  Even though you follow the install directions, you have to play around with it a little so that you are perfectly comfortable.  

What type of wdh do you have? Most of the wdh also have a provision for anti sway. You may already have part of what you need. If your wdh has the ability to add anti sway bars, this would mean simply adding the bars and the associated bar receivers to the a frame of the pod.

You did not mention what you're towing with. That can have a big effect on how your "system" will deal with sway. Also, how you load the pod will affect sway conditions. Best to know how much weight you're pulling and how the weight is distributed.
