After months of worrying and considering the options, I finally went ahead and bought a load of stuff from Ulli at
http://www.california-camping.de
This included a full set of Vinyl and Alcantara seat covers for my 3 seater bench config. beach, tailored carpets, front to rear, and Ulli's back window storage system.
Seat Covers - These are properly amazing and have transformed my Cali's interior. The front, captains chair cover's took around 30 minutes each to fit with some scrapped knuckles along the way, and look as if VW created them, and the rear bench seat took another hour or so to fit, again fitting and looking like they have come from the factory.
It is truly amazing how good these look and despite the significant effort to fit them, I recommend them whole heartedly.
Carpets - Again beautifully made, with bound edges and a lovely deep look. Finally getting the living area in the back covered makes for a much more cosy and inviting space. The mid and rear (boot) carpets are a perfect fit, the small slither of carpet by the sliding door entrance is supplied with velcro, but I have yet to feel the need to use this.
The front (cab) carpet was, unfortunately, the reverse pattern of a California Comfortline with the different LHD dash, and so the fit is not perfect, however, Ulli has now got the correct shape and will be sending me a front one-piece carpet in the next few days. I will update this post when I receive it.
Now the bad news for 3-seater Beach owners wishing to carpet the living area. The deep carpet is just a little too deep and luxurious, the drawers that live under the bench seat are now a very tight fit, and need to be slid out and put back in the top position to make it possible to move the bench, or convert into a bed. Personally, I can live with this, but it is important to understand this before making a big purchase. It is my understanding that the Brandrup carpets also fowl the drawers, but I have not witnessed this myself.
Window bag system - When these arrived I was initially not overly impressed, the quality is OK, but the bags seems oddly constructed, and just, in some way, clumsy.. however, having fitted and now used them, once in the window positions they become an incredibly useful and additional space for food, clothes, towels, teddies or indeed anything else you can think of, and the best bit is that because they look as if they are supposed to be there, they make the van seem tidier in some way.
We have emptied the side pockets beneath the sliding window, which after a year of use had filled with all manner of unsightly things, and put most of that stuff in the window bags, which just makes everything seem more organised.
So expensive, but in my opinion, and for the way we are now using our Beach... again recommended.
Please find attached a few photo's of these items, but if anybody has any specific questions, please post them here.
