Thanks for the information everyone, its been useful to know what others are towing ... It looks like we are going to go with a 2010 Swift Challenger as it ticks all the boxes we wanted on internal layout, its newer than we were going to go, but its got a motor mover fitted and has the Alko Chassis with ATC and a few other extras in the deal ...
Cant wait to get the car back from the garage and take delivery of the Caravan in a few weeks
