Hello Paul,
It is very difficult to gauge the exact performance of caravan manufacturers in respect of the quality of delivered caravans, because as you say, those customers that are satisfied have no reason to comment, and after all why should they?
But the problem is, it is clear from forum's like this one there are enough owners who don't get that same satisfactory experience for it to be a serious concern. It's also a little fudged, becasue there are some caravanners who will accept some minor issues without question, and there could be many reasons for their lack of complaint.
It could be a really minor issue like finding spare screws or sawdust in bed locker, and its so easy just to remove them. its not worth complaining.
There are some caravanners who have come to expect there will be some issues with a caravan like a draw handle not full screwed on or carpet not fully trimmed, etc and are prepared to undertake rectification work them selves. etc or who are satisfied with the dealers actions to sort it out.
The art of good customer service is to be able to convert a customers negative into a positive. - its actually quite surprising the number of household names whose reputation is actually based more on good customer service, rather than the quality of their products!
Even though some caravan issues are so small they are still technically a fault becasue the product is not perfect, and that is in breach of the dealer's legal obligations under the CRA. Customers should really be making that point far more often to dealers, to keep them in mind of their obligations, even if the threat is not carried through.
The reality is that despite the protestations of caravan manufactures who will claim their products are highly technical, in the grand scheme of things they are not, compared to television, computer, or a car they are comparatively simple assemblies, yet look at all the three aforementioned products, and look up their respective reliability and there is a marked difference in customer expectations of it working correctly first time out of the box and where issues do arise, its simpler to get it sorted or the way the suppliers are far more proactive and constructive about dealing with it.
If those other industries can get it right so often first time with highly complex products, why can't caravan manufacturers do the same with technically simpler products? More to the point why should customers have a lower threshold of satisfaction for caravans than other products?
It is my suspicion that if caravanners were brutally honest about faults they find with their caravans, the level of complaint would be substantially greater than it is at the moment. It is partly the the public's perception that caravans are historically frequently faulty which has lowered their threshold of satisfaction, and that is seen as validating the industries current poor practices.
I can't deny that sometimes a caravan may genuinely be perfect, but based on what we see on the forums and from professional experience in a industry that supplied caravan manufacturers, I'd say it's a rarity rather than the norm.
Could caravan manufacturers improve? The answer is a definite yes, but they first need to accept that they have a real moral obligation to their end users, rather than trying to distance themselves by using dealers as the punch bag in the middle.
