We tow a Lunar Lexon EB, haven't used the 3.0l yet but the 2.7 had no problems towing, mind lunars are fairly light caravans.
I did tow my mate (Landrover freelander)who was attached to his brother in-law (Vauxhall Zafira), which he had lost on a bend and ended up down a grass embankment into a ditch.
My mate tried to recover him using the Freelander, but he got stuck, so he called me and I pulled both vehicles out at the same time with the 2.7.
The AA man who had been sent to assist, said he wouldn't have believed it if he hadn't seen it with his own eyes.
