T6 LWB Caravelle for me.
I run it with all the seats in slide the bench forward a bit and if just me wheels off bike upside down and and in it goes, sometimes a couple of straps but not essential. Use a bit of old bike box on floor and to protect the seat back.
Also got a home made pressure washer in the back with 25l water – all fits easily with a few tools etc in the back.
Means loads of space to get changed in the back in shite weather. Old sheets on the floor if particularly nasty out.
As Scutler mentions just beware the roof lining.
In someways a van would be easier but quite honestly I love my setup, finish ride, fire it up, wash the bike, and usually its warming up nicely as I load the bike in to get changed.
If me and a mate go away the bench only needs nudging up a bit more. And for holidays with the children use a bike rack.
Have fun, I love mine 🙂
