Hi baranigirl, Saw the damage, if your repair dose not work out, then look at the adds for the caravan breakers, as I have seen them asking for the chassis of the caravans they break up to be taken away Free of charge,so if it comes to the worse case the chassis is duff, then that could be good alternative and free. Something to keep in mind.hope that is of some help.
