I went from a SWB T4 Kombi to a LWB T5 Kombi.
SWB was just like an estate car, anywhere say a passat could park, the van could go.
LWB, the extra length is noticeable, the turning circle is bigger, there is one local multi storey car park which is a pain with the new van. It’s not a car-like parking experience any more. I’ve fitted a reversing camera, I might add sensors too.
But for bikers, I reckon LWB is the way to go. Easy to roll 5 bikes in, wheels in and just go. SWB involved wheels out and faff. The extra space is really worth it.
We looked at caravelles – far too expensive, plus fluffy carpet to destroy with dirt, and taking any seats out is a 2 man job. Kombi + insulation + carpet lining is the sweet spot I think.
EDIT – if you do want to lower, read up on T28/30/32 differences.
