Unfortunately it is not unique to Eldiss, one member has had side panel repairs by Swift on a very new caravan. Seems like winning the Lottery gives better odds at times.PXd our lightly used 3 year old Elddis last year after the side started falling off and elddis washed their hands of it (it was our fault apparently).
Wouldn't touch an Elddis / Edwin Hymer group product with a barge pole.
