I have just bought a 2008 Alphard.
The plan is to use 5 of the 7 seats and use remaining space for a weekend camper.
My conversion cost me under £500.
* Remove rear 2 seats (third row).
* Add 2 side storage pods (Ebay £224)
* Camping hook up (Halfords £20)
* Rechargeable LED lights
(Amazon £19)
* Air Fryer and portable gas stove (Amazon £66)
* Fold-out bed (Amazon £49)
* Extra materials - melamine panels, cables, double power socket and connectors.
* Will post a selection of photos to show the finished result.
