John, we have a 2008 Challenger 560. Within months of purchasing our caravan from new, Swift authorised our dealer to replace all the pleated blinds in our van, due to them all being peppered with pin-pricks along the creases. It is a well known problem and the blind manufacturers supplied new ones, using a thicker material, which, although very similar in appearance, have a larger pattern on them than the original ones.
After paying several thousands of pounds for our Challenger 560, we have been disappointed to have experienced problem after problem, some of them quite major, including having to have all the front windows replaced soon after purchase, due to another known problem when the window panes were manufactured too close together, resulting in the panes flexing and touching, especially after motorway driving, leaving white contact marks on the windows.
Two weeks ago, we were on a CL when we noticed 'bubbling' of the wall board under the front nearside window due to water ingress, which is going to be fixed by our dealer at the end of this month.
We would have preferred to have had NO problems with our caravan, of course. But, almost all the faults we have had have not been Swifts fault, but the fault of the supplying manufacturers (windows, door lock, upholstery, blinds etc.) and Swift have responded to all our problems by instructing our dealer to sort them out immediately.
A lot of the problems we have experienced with our caravan could have been picked up with more vigorous Quality Control by Swift (for instance the microwave wasn't fixed to anything and almost slid out of the housing after one trip). It may be a good idea that workers fitting out caravans have to sign for work they have done.
I suppose we have been lucky that we have a very good dealer which has been supported by Swift.
