No side doors, no bulk head holes for longer poles in roof, no water heating system.
What's your problem? :

That's more kit than I've got.
I've got a tank (wonky)
A pump (bolted on the side of van)
Battery (in a basket cable-tied to the side)
Two poles (rattling about in the back)
A washing up tray to put my brush in.
No protection stuff on the floor.
...and so on...
Going to slag it off (in a 15k van)?
Who cares? I can do my job as well as you or anyone else.
Does it make you feel important if you've got loads of crap in your van?
