I mean specs on the tow vehicle. You'll need a Class III hitch - and you'll want a vehicle that was built with intent to offer one.
A good idea would be to buy your tow ball from a specialist - like one of those U-Haul stores that installs hitches. They'll probably walk outside and look before recommending what ball and drop/rise to use.
And are probably hard-wired to tell you if they see a concern. Or talk to any long time boater.
Also, drag out your vehicle owner's manual and read about your tow button. They sometimes have load ranges where you don't use it with an empty/light load.
There are likely message boards out there for those trailers.
The real fun comes from learning to back up a tow load. Any experience there?
I recommend your nearby abandoned mall parking lot with lines painted on the tarmac - and nothing you can back into.
