I am capable of fitting it myself but allowed them to fit it.
Yes that's the system we had fitted in it except we had split charge relay fitted. We had storage fitted as well but they took the photos before it was fitted lol
On this van we had the floor done with speed liner and yeah i can see why its expensive. First van i have had done with it, very impressed with quality.
If you do go down the grippa route let me know will try and meet you, only 10 miles from them

Van handles 500L fine and drives just like a car.
