Kate,
You have my full sympathy, I know just how you feel. Our Crown had the same problem last year water in it and with a holiday booked our first ever 2 week one, to Holland.
The repaiers then had the van for about 2 months, but just managed to get it done in time, by one day, so we were lucky.
The van had another serious leak whilst under the repairs guarantee and was back in for repair on the 5th Jan this year, we finally got it back only last week.
Admited unlike yourself we were not using the van, whilst it was in both time, but can fully understand how you feel and the length of time taken for repairs to be done.
If caravan makers made them properly in the first place, none of us would ahve these problems and disappointments.
Our own van which we bought new in 2001 first new van we ever bought in over 25 years caravanning, has been the biggest pain ever.
Not a trip out with it has there never been a time when soemthing either bent, broke of stopped working. Is the explorer group interested, not on your life, their attitude is tough get on with it.
The van has spent more time with the repairers than we have using it.
Now I've had my moan, I do hope that you can get your van sorted ASAP and start enjoying some quality time in it. But as I say, all this could be avoided if they we made as they should be, rather than flung together from a great distance.
Good luck,
Ian.
