not really and answer to your question but........my son and i both have ww's
they both have just over 6 ft under the rear bed when up. he has a rzr also and works for him.
this seems to be a sort of generic measurement.
yu are right to ask and check to make sure though.
the 1/2 ton and 3/4 ton ratings have all become so blurred, so much in the last few years, its hard to keep up with what will pull what.
i think most of the ultra lights ect are built to be 1/2 towable. you very well might want to take a test tow before you buy. if at all possible. if not at least hook up and see how your pu looks. measure hitch sag and front fender hight be for and after.
that and the gvw of the trailer should be posted some where in the trailer. you can compare to what the rating on your tundra is.
