So funny reading the comments of those who've never owned one
I've owned several Transporter vans in various guises, with and without pop top roof, and 3 other motorhomes too, and now a GC.
I'll say it how it is, as of course there are pro's as well as cons.
They won't suit everyone, they aren't nearly as easy to drive in tight lanes and there will be some parking sports you can't get in to. The lounge area when at max capacity is bigger in a standard Cali/transporter.
However, an on-board bathroom is a must for me, and my two girls, I really don't like the condition of most 'shower blocks' plus we can stop anywhere anytime and of course go to the loo in the night.
Driving the GC is a real pleasure and although we have the 600, can park in just about any space. It isn't too much wider than a cali, although you have to pay attention to low bridges and in Europe roads can have low barriers on them.
The driving range is poor at around 400/450 miles as it only has a 75 litre tank.
You can jump into bed at any time, and the extra storage space is not to be missed, as it has a very large capacity compared to a standard cali, which always frustrated me packing everything away just to move. In the GC if it's raining or you're lazy you can literally just throw everything into the garage.
The LPG storage is huge and you could go weeks before refilling.
The standing height is a real boon too whether you've just pulled over or have parked up, it's instantly there.
Finally, we moved away from a pop-top as we like to travel around and when it's 20 degrees in the day in Spain late in the year, it can be 5 overnight and it was just too cold to use. Not so with the GC.
They'll be plenty of people who'll tell you, you don't need a bathroom and what they own is better, but only you can decide what's right for you.
Unfortunately most people argue a debate from their perspective, and will post laughing emojis or try negate your point if you disagree with them, because god forbid anyone should have a different point of view, but their life could be vastly different to yours. They could be single, a couple, retired, have pets with them, a family of 6 etc. etc. No two situations are the same and no two vans suit the same people.
