It did strike me that the faults the owners complained of in the program were so 'normal' in the industry that it was a little bit unfair to single out the one specific manufacturer featured.
Whilst I do agree the whole industry still needs to wake up to the reality of poor quality, and to react more positively towards customers who suffer as a result of their negligence, Your comment is an appropriate approach from someone who is not directly involved with this particular case.
But from this particular customers point of view his problems are with the product he has, and rightly so his anger should be directed against the manufacturer, and of course legally against the seller. Morally the manufacture should be ashamed of these issues.
I know from my own experience that whilst OEM products installed in caravans/motorhomes, do sometimes appear to be faulty when the customer receives their new caravan, in many cases the faults have been induced by caravan/motorhome manufacturers poor handling and installation of the OEM products.
I can well understand why caravanners with faulty caravans blame the manufacturers, and I agree they are the prime source of most of the issues, but the dealers are not innocent and are of course legally responsible. Dealers should be refusing to accept faulty goods from the manufacturers, and they should also be doing the proper PDI well before the customer is due to collect so the faults can be discovered and put right. That is what they are paid to do, and if they are not doing it satisfactorily they are in breach of contract.
