Sway bar FAQ

I'm not sure if I'm posting this in the right place, but I have questions about sway bars. We currently have a pop up and are planning to upgrade to a TT (probably something in the 20-25 foot range) in a year or so. I've read where people talk about sway bars, but haven't had much luck finding a basic primer on the what-and-why about them for a newbie.

Some of my questions (and feel free to add others if there is something that I should be asking but haven't)...

1 - Do I need one for any TT, or is there a weight threshold where it really doesn't make a difference.

2 - From what I understand, they are used to stabilize a TT being towed in wind (or maybe even around passing trucks). Is that correct?

3 - How do they work? Are is it a passive mechanical system or an active electrical system (or a combination)?

4 - Does the equipment only work to stabilize side to side movement, or does it do something for vertical movement as well (in one message I read, the person said that they used air bags).

5 - Is there a web page I should be looking at so I don't ask a bunch of basic questions?

Just a friction sway bar works by making it harder for wind or passing trucks or anything else to cause the trailer to sway. Towing a full height TT feels a lot different from a pop up and the wind has a lot more square footage to push against. I recommend a sway bar for any full height TT.

These sway bars are passive. You hook it up when you hitch up.

A better option than friction sway control is built in sway control in some weight distribution hitches. These prevent sway rather than try to control sway. If you don't need the WDH then just a friction sway bar may be all you need.
