i have the simbars one that bolts to the spare wheel , worried about putting too much of the weight on back door though so i put the three kids bikes on that , and put me and hers on the roof rack , towbar type will take the weight better but makes it kinda hard to open yer tailgate , although i did see a tilting one somewhere that folds down flat to the floor while yer open the boot , then yer fold it up again to travel .
