Hi Pete
It drives spectacularly well and just as car-like as the T6. You’ll be very much at home and familiar with all the controls, although the cruise control is a little different.
Being a converted van the challenge is always going to be noise, there is a lot of kit in mine so it’ll never be as quiet as a car, but it’s pretty damn good.
As for size, mine is an L3 H4. My logic went like this..
With a T6, if you put a pop top on it, then you exclude yourself from car parks with 1.95m overhead barriers, although you can squeeze under many which are 2.05m.
You buy a Crafter for the extra space, so it’ll never fit a 2.05 barrier, once you realise that then actually there’s no point, you might as well go for it height wise.
Width is by far the most limiting factor in drive/usability.
I live in London where 6’6” limits abound, and crafter and sprinter delivery vans are everywhere, they have no trouble either getting around nor parking and they are mostly LWB(L4) length. EDIT. - and it does go through a 6’6” limit too.
The length does take some getting used to as you have to pull further into junctions to get around, so needs more planning. The turning circle isn’t as good as a T6 either which doesn’t help.
I've recently parked in an a Pay and Display car park and to avoid the wardens bought 2tickets, but I hogged 2 bays (1 in front of the other) EDIT, I did had a Motorcycle on a trailer at the time.
So to sum up, it’s a compromise, but we both love it. It’s not as quiet as a car, but it’s easily liveable, and road noise is quieter than my T6 with XL20” tyres.
Why no take one for a test drive and see for your self.
