Hello together, we decided to install a rear bike carrier, we know about the possible disadvantages in the load distribution, but due to various circumstances this is the only possibility for us. Our caravan is an Eifelland Holliday 495 TF, year 2006/2007, was unfortunately not available, therefore just Knaus/Tabbert, but this only on the edge. Does anyone know here the events in the substructure, i.e. does someone know if a strut is under the rear window? If no, would it be enough to install a corresponding reinforcement (wood slats, metal profile, etc.)? If someone has experience here, that would be great. Thank you for your help.
