Hi and welcome to the forum! Your sig doesn't say what your Tow Vehicle is but those trailers are going to have tongue weights in range of 1,000# or maybe more. Put another 5 or 6 hundred pounds of people and gear in the TV means you need a load carrying capacity of pushing 2,000#.
In other words forget about manufactures towing capacity ratings. You run out of load capacity long before you hit that tow capacity due to the heavy nature of TT tongue weights (12 - 15% of loaded TT). Those trailers are 3/4 ton needed.
