Coming from a T6 myself, I found the Crafter to be a very easy and comfy drive and I too have the 140 LWB. But I’d recommend test driving a LWB before buying as the turning circle can be a PITA, it’s pretty poor. It didn’t me, but it might put others off.
Also, just to throw an idea in, keep an eye out for a super high roof. It’s a game changer in terms of inside space/ layout design. It has a very robust fibreglass roof, and is totally smooth on top, making solar and vent fitting so much easier.
