Hi there
We're serial vw campers. We're on number 5 at the moment.
Ours is late bay twin sliding door tintop which came with no interior when we had just 1 baby sized ds and we kitted it out with a full width rear bed - snaffled from a doner westfalia.
Its not a walkthrough and has a half height solid bulkhead behind the front seats so we have built in a kitchen unit that backs onto the bulkhead.
We have three camping trips planned for this year - Wales, Cornwall and of course 'Vanfest'.
DH ds2 and myself will kip on the fold out bed (which is huge and really comfy) and ds1 is to get the brand new JK cab bunk (he's soooo excited about it).
We also have a tunnel awning which we have used to sleep in when camping with friends and also serves as a great dining/sitting room.
Best campers we've had for kids were the westfalia (lovely big bed in the pop top) but we decided not to keep it after lovingly spending years and ££££ restoring it, as with the kids and 3 dogs careering in and out, it would not have stayed beautiful for very long .... and the Dormobile which had a great side lifting pop top and two fantastic pull out bunks across the sides.
We have loads of fun in ours - 'he' is very much part of the family and we've had 'him' longer than any of the others 'cos the kids won't let us sell him and get a 'walkthrough'. 'He' is definitely the tattiest van we've ever had as well (mainly due to us being broke since we've had kids!!) but we've just decided to go with it and have put great big flowers down the side!
In our experience the best way to find out about useful layouts for interiors is to go to plenty of shows and talk to the other owners. Most people are desperate to talk about their vans and will be really keen to help. You could also try googling vw camper interiors etc as there are literally thousands of vw sites out there.
Agree with Surfette VW vans are loads of fun and its great to see at the waves and smiles you get when you're out and about.
