Poor customer service when they don't feedback the reclassification failure. Appreciate without doubt your excellent conversion is for all intent purpose a motor caravan BUT.
V1006 Motor Caravan Checklist:
2 or more windows on at least one side of the main body (does not include windows on drivers or passenger doors) to provide a reasonable amount of daylight into the living accommodation.
Is No1 of the 5 criteria on the checklist that you don't have and possibly failed classification on this point. Can you put a slot window or a port hole one in on one side?
I disagree with your interpretation, due to badly written and ambiguous rule to be honest.
The rule says "2 or more windows on at least one side of the main body"
My interpretation, is that means 2 or more windows in the rear of the van, excluding rear door and roof - e.g. on at least one side, and could be one side or two sides. So a total of 2 or more windows on "the sides".
In my view, if they wanted a minimum of 2 windows on one side, they would write "At least 2 windows on one side" and left it at that.
Ambiguous.
No worse that the other rule:
- an awning bar attached to either side of the vehicle
Does that mean either side as in offside or nearside; or either side as in both sides!!
Or "must be a high top"
How high? Is H2 high top? Or H3? Whats the minimum internal height? etc
Regardless, the design is how I want the van and I'd not put another window in as it'd compromise what I want. So if thats *it* then I'll take it on the chin.
(Also there are pro motor caravans with one one side window on each side (and some on the rear, but they don't count no matter how you interpret the rules) - and some self builds with the same have gone through, and a great number with 2 windows on one side have failed! No set pattern or consistency)
TBH - you could be right, but the rule is there to ensure sufficient light enters the vehicle. With 3 skylights as well as 2 side windows, it has plenty. That should be the judge! I guess I could remove a window and put 2 smaller ones in on a ply panel
