Maybe I can chime in on a bigger van experience.
Crafter-based Knaus Van Ti 640 - Roadsurfer Edition. It's a 8spd automatic mated to a 177ps 2L TDI on a 3.5T chassis. 7m in length, 3.1m in height (roof mounted AC adds few centimeters).
I must say this versions of the Knaus is custom made for Roadsurfer as it has a flat floor inside and additional overhead storage shelf, plus few additional decors. I rented it last minute because the camper I nearly bought, got sold from under me and I had summer holidays in Poland planned.
I absolutely can not stand a camper that does not have a flat floor, as we have a dog and having him falling all over the floor when he is moving about trying to find place to sleep is a no go. We keep a dog bed behind the driver's cabin, as you can see on the pictures.
Fit n finish is quite average, maybe a step up from GC but my van has had the shower door handle installed backwards making exiting the shower a bit tricky.
The skylight shade/screen literally came loose from the roof by it's securing bolts. It feels like the bolts are stripped out as I tried to tighten it but the bolts next really go tight. Aside from this most of the cabin is rattle-free, except for the stupid Reimo door blinds that must go - rattle is absolutely horrendous.
Bed in the rear no complaints, as is the bathroom - 2 shower drains and 100l of water fresh/Grey was nice. Largest Thethford cassette toilet, very nice. The biggest selling point for me is a huge refrigerator/freezer that works wonderfully. My wife was blown away by it as well with the pull out drawer inside.
Massive garage that can swallow bicycles.
Air suspension in the rear makes leveling a breeze.
Two person bench that extends for more elbow room is nice, but for long drives it's too upright. I can't comment much on the inside table however, as we tend to dine outside and our large Labrador has his sleeping den inside.
Fuel economy is around 11.5L/100km at 120kph indicated - 114 GPS speed.
Let me know if you have any questions. Having driven this and the GC 600, I would have to be crazy to buy the GC over this van and prices in Germany are quite similar.
