I've towed: a twin pack of jetskis, a SeaDoo Sportster (boat), a utility trailer with a Dingo in it (about 2000 lbs). I've never had a problem with the capacity.
One member was trying to use a 'basket' for his stand up jetski in the hidden receiver & noted some flexing of the rear bumper.
Remember, there are two ratings associated with hitches: tongue weight and draw weight. Tone's hidden receiver can handle as much draw weight as the VX can. Tongue weight is the limiting factor. I've put more than 200 lbs tongue weight on mine with no trouble but the 300 lb jetski mentioned above seemed to have exceeded the limit.
If anyone has a Tone hitch that they have not mounted yet, I can probably get 'welder guy' to copy it. Lemme know if there is any interest.
