I've never been asked for age of van, ours was an 81, I decided it was an embarrassment outside and swapped it for a 96, still miss the far better inside though.
I doubt they just dream up rules which would lead to making less money, the problem is owners passed experiences, our site owner can spot a pikie at the end of the road, the dogs then out waiting if they try and turn in. As it happens he would not allow you, it says so on the gate, one of the reasons he told me was early starts waking the rest up.
As you've found though, once they meet 'you' then the rules don't necessarily apply.
What will always apply is the law regarding reselling electric, this simply states not a penny profit on what they pay, any infrastructure costs for meters etc must be added to the pitch fee.
