She'll get away with something quiet light to tow just 1 Icey. They are only around 350kg I would say. Personally I won't tow a light trailer because they scare me, I like my trailer to have some weight to it. A Freelander would be a good option cos they are nice to drive and reasonable to run, but can pull a trailer and pony quiet easily.

I'm struggling cos I need to pull 2 heavy cobs and a trailer...unfortuantely I'm looking to have buy some huge monster 4x4 to do so which will cost me a bloody fortune!!! Might be better off getting rid of the horse instead!! (That's a joke cos he's going nowhere!!)
