well the vw rear seats cost a fortune! about 1300 if memory serves but as i'm not ever gonna sit there i didn't want to spend that money. i did want a pair of single seats upfront though so it made sense to move the double seat to the rear giving 4 seats in total although it's rare for me to have more than 3 of us in the van so comfort should be fine.
the space is also useful at the mo and long term i could fit a sink/cooker/fridge/units etc so we'll see what happens long term as to what changes or upgrades i might make. the way Jon built it is so that it can be changed easily, that's how he likes to do things, even with his camper conversions each is individual to the vehicle and made to measure as opposed to a fixed pre-built unit that fits in from the back.
as it is it leaves scope for change
