Towing capabilities of Vauxhall Antara

pterodactyl

At present I tow my Bailey Unicorn (MTPLM 1723 kg) twin axle with a Kia Sorento but am considering buying a new Vauxhall Antara SE 2.2 4x4 (188 bhp). The towing limit is 2000 kg but the CC matching guide raises a yellow flag re caravan/towcar weight ratio.
 The CC matching guide says that this can be done but with care. I would be grateful to hear  from anyone who tows a twin axle with this type of towcar
