Judging from what you say you have, i'd guess you'd be over. And therefore need a B+E.
I use a Mondeo Estate(No abuse please)
towing a twin wheeled trailer, but i only ever put small cars on it, likes of Corsa B's, Saxo's, and any other light, usually french sh1t.
I once put a Golf on it, and thought i'd be up on my weights so my dad drove as he has a C+E so was well in
