Hello 06032!
Little advise. Take it or not, it's your call...
The trailer + the 3-Wheeler will be over a ton weight. One axle? I wouldn't... try to find a 2 axles trailer if possible.
Comments about the trailer we can see following the link:
1 - the big matter: the balance point. If you buy a trailer such as the one in the picture, with the single axle quite far at the back. and load your 3-Wheeler looking forward, you'll have a huge tongue weight on your tow ball. Unless you have a massive RAM or F150 pick-up or any other towing beast, this is no good at all. You'll overload the rear axle of your towing vehicle which implies making the rear suspension and brakes suffer too much. And the steering will be also affected. I insist this if you have a regular SUV or medium size truck. If you have a monster, this may not be the best trailer, but your beast may not suffer that much.
2 - The one shown in the picture has not overrun brake, I would say it's mandatory! The trailer + the 3-Wheeler will weigh more than a ton. And that's a huge weight to tow without an overrun brake. Here in Europe this is forbidden.
3 - Highly recommended: anti-sway damping device.
I don't mean to disappoint you with the trailer you're looking at (I mean the one we can see following your link), but I’ll try to have at least the characteristics I’m telling you.
If you’re curious, have a look at my blog, where I just explained about my tailor-made trailer. It might help you to choose wisely.
