Any ideas on how to turn a T6.1 LWB 5 seater to a 6 seater or 7 whats the best way. I want to keep my Captain seats. Many thanks
Not sure what you mean, but...
the frame is built for 9 seats (3 for each row). I have in fact a 9-seater Kombi (German wording, would be probably a Shuttle in the UK), while I don't actually use the last row.
The second row has always at least one single seat ( i.e 2+1 or 1+1+1 ) near the sliding door that can be tilted or removed at all in order to access the third row.
So you can easily get to 2+2+3, providing that you have all the floor sockets installed for third row of seats. Otherwise you can buy and install them, it is some work, but some people has done that.
Same goes for the safety belts.
A special case is the Multivan T6 (I think is Caravelle in the UK) that has sliding guides for the rear seats where you can more flexibly arrange them.
Depending on what seat configuration you have currently on you papers you may need to get it approved by UK traffic authority (no idea which one) , your papers updated and your insurance too.
