Well Adrian,
I tow with the same car as you have an 06 2.0d4d, i pull an 07 Bailey Pageant Series 6 Bertagne, at 1420kg dont load it to the max. I know Toyota only recommend a max of 1300kg but i find it tows well with a full car load and caravan hitched. the only concern i have is the back of the car is inclinded to ride very low so watch your nose weight.
