The main reason I have the 110 is to tow the horse trailer. Before now I have towed with a citroen 1.9 diesel. It managed the pull but if the nag decided to have a wiggle around in the trailer you sure felt it. In the 110 the beast can break dance and it still feels solid.
I did look at some of the other 4x4's but most of them had too low a limit which made me nervous. The only time I have ever had a trailer waggle the car was on the motorway and it was behind a car and really not a pleasant feeling.
So from all (and to get to the point) don't look at the theoretical limit the manufacturer tells you and use something that is made for the job
