Welcome from the Eastern Coast of Canada. I hope you have a lot of fun with you Pod. There are a lot of posts on this forum about this question and I encourage to to read them but the short answer is it depends on what you are towing with.
You have three options you can get an antisway bar that will stop your trailer from swaying back and forth in the wind. You can also get a weight distribution hitch which distributes the tongue weight of the trailer more evenly between the front and rear wheels of your tow vehicle so it stops the back of your tow vehicle from bouncing up and down and helps to keep you front wheels firmly on the ground. Your third option is something like the Equalizer hitch which does both.
Now what do you need. If you live in an area that gets a lot of wind and your TV (Tow Vehicle) has a short wheelbase I would recommend that you get some sort of sway control. Also if you are towing at more that half of your TV's Rated towing capacity I would recommend a Weight Distribution Hitch. I am towing with a 2009 Jeep Liberty which has a fairly short wheelbase but It has a 5000 lbs towing capacity so I could have probably gotten away with just antisway bar but I got an E2 hitch which is similar to the equalizer hitch because it makes it more comfortable to drive. These are just my opinions and I am sure you will get many more
Half the fun I have had with my pod is figuring out what to get for it next so have fun and stay safe.
