thanks for that.Here is a link to the brochure for 2011 sprite
which does suggest that cycle mount bars are fitted to the rear panel. So hopefully this is the case with your specific van.
In which case you should be able to add a rack like one of these -
although be careful of what the weight limit will be and the effect the added weight at the rear will have on the noseweight of the caravan.![]()
