Hi Dave,
Wondering if you can help, I phoned them up to change the order to the 2 season pack, I mentioned that it was for a VW T6 van and they mentioned that their Duvalays are becoming more popular with VW customers and that they made a 58cm version specifically for the VW's... though its not on their website.
Sounds ideal, however, you obviously lose a bit in space (standard is 68cm). So yes, I'm a bit torn, the extra 10cm I guess is ideal for if one is on the RIB or pop top, though I guess two 68cm together on the RIB would leave a lot of overlap. She mentioned on the phone this might be an issue with trying to tuck the memory foam down the side. That said, there is a fair bit of space on one of the sides.
Yes, bit torn, 58 or 68cm.
